Lenovo IdeaPad Yoga 11S vs Dell XPS 11 vs HP Pavilion TouchSmart 11z:Who is the winner?

 W.A.Khan,                                                                                                                                                 Lenovo IdeaPad Yoga 11S                                                                                  
The Yoga 11S is one of the most anticipated laptops of the year, especially after the very warm welcome its predecessor received. That predecessor, the 13-inch IdeaPad Yoga 13, was one of the most talked-about Windows 8-launch laptops. The Lenovo IdeaPad Yoga 11S is a great 11-inch ultraportable touch-screen laptop that also has a flip-around display for tablet and hybrid use.The 11.6-inch IPS display impresses with its vivid colors, and dark scenes greatly benefit from the Yoga 11S’s deep blacks. The 1366 by 768 resolution is a bit of a bummer in tablet mode, but it holds up well during laptop usage on account of the system’s small screen. An overactive ambient-light sensor proved annoying, though easy to disable.             Battery Life:                                                                                                                                               The battery life of the Ideapad Yoga 11S to be pretty good but not outstanding. The battery lasted five hours and 26 minutes in the Powermark, which mixes web browsing (50%), video (25%) and productivity (25%). That’s around 25 minutes less than the Samsung Series 7 Ultra mentioned above and nearly 50 minutes less than the Sony Vaio Pro 13.                                                                                                                        But,Recent 11-inch laptops from Apple and Sony have raised the bar for ultraportables, especially when it comes to battery life. The Yoga 11S needs an upgrade to Intel's latest processors.
The bottom line: Like the larger 13-inch model, the 11-inch Lenovo IdeaPad Yoga 11S is a useful hybrid that doesn't forget it's a laptop first, but it's stuck with what feels like old hardware for now.                                                                                                                                                                                            Specifications

You don’t get to tablet mode by separating the display and keyboard bits, you do it by turning the screen around 360 degrees.With the Dell XPS 11 2-in-1 you’ll be working with an 11.6-inch display with, again, Gorilla Glass to protect your innards. This display works with a 2560 x 1440 resolution and works on a hinge that allows you to fold it back 360-degrees. As you can imagine, this display is also touch-enabled and works as both a notebook and a tablet - when you fold it back, that is.The Dell XPS 11 is a slim, light hybrid that looks and feels great, and offers decent performance and battery life.
But, The touch-style keyboard, lacking actual keys, is an experiment that just doesn't pan out.
The bottom line: Attempting to out-Yoga the Yoga, Dell's flip-screen XPS 11 has a great design, but isn't as practical as other hybrids for actually getting work done thanks to a frustrating keyboard.                                                                                                                                                                                                     Specifications

 The touch pad is a decent size for an ultraportable laptop.Instead of the more popular clickpad-style pad, this one has separate left and right mouse buttons. You lose some pad surface area, but it's probably easier to get definitive left and right mouse clicks when the multitouch response on the pad itself can be a little sluggish. The HP Pavilion TouchSmart 11z costs very little for a touch-screen Windows 8 laptop, and it has excellent battery life.HP Pavilion TouchSmart 11z has dimensions of 11.4 x 8.5 x 0.86 inch and weight 1.54 Kg making it easy to carry and lightweight. Graphic quality no doubt, because it has been equipped with AMD Radeon HD 8180 so the play gaming will be satisfied and more smoothly.
Battery life:                                                                                                                                                   Battery life tests, in which we disable power management, enable Wi-Fi, maximise screen brightness, and loop an Xvid-encoded video, the Pavilion 11 Touchsmart lasted 3hr 45min, which is a little longer than most mainstream (and more powerful) Ultrabooks that use third-generation Intel Core CPUs — the LG Z360 Ultrabook, for example, got 3hr 24min in the same test. You can prolong the battery life by lowering the brightness or by setting the screen to dim or switch off during idle times, but how long you get out of the battery will still depend on how you use the laptop and how much you work the processor (it fluctuated between 15 and 21 per cent for our rundown test).
But, Occasionally sluggish performance gets frustrating, and more-powerful PCs are available in this price range. The bottom line: HP revives an 11-inch favorite with the Pavilion TouchSmart 11z, but there are better performance-for-money deals to be had.                                                                         Specification:                                                                                                                                            Processor AMD A4 A4-1250 / 1 GHz ( Dual-Core )

HP Spectre 13 Ultrabook vs Lenovo IdeaPad Yoga 2 Pro vs Apple MacBook Air:Best Is..........

 W.A.Khan,                                                                                                                                                 HP Spectre 13 Ultrabook                                                                                                                         The HP Spectre 13 Ultrabook is a Windows 8 laptop featuring a 13-inch 1080p or QHD resolution touchscreen, Intel Core i5 or i7 Haswell processors, wide touchpad with gestures, and a 9 hour battery life.With a 1.6-GHz dual-core Intel Core i5-4200U processor, 4GB of RAM and 128GB solid-state drive, the Spectre 13t is a lightweight speed demon. We opened multiple tabs in both Chrome and Internet Explorer, streamed music from Spotify and watched Netflix without any slowdown.The HP Spectre 13 has a sharp, thin, ultrabook design, high-end upgrade options, a great keyboard, and an extra-wide touch pad.
But, A handful of other premium ultrabooks offer better value. The extra "control zone" spaces on the touch pad don't feel like a fully realized concept.
The bottom line: The HP Spectre 13 is an excellent all-around ultrabook, with a great keyboard, display, and battery life. The unique Control Zone touch pad is interesting, but I wish it were a little more useful and intuitive.                                                                                                                                                     Specifications

This new model adds a backlit keyboard and an impressive 3,200x1,800-pixel-resolution display, while keeping the price under $1,000.The impressive specs continue with an up to an Intel Haswell Core i7-4500Y processor and up to 512 GB SSD. There's also up to 8 GB of DDR3 RAM.
But, In battery life it lags behind a couple of more expensive higher-res laptops, some of the hybrid modes are of dubious use, and Lenovo still doesn't know what to do with the keyboard in tablet mode.
The bottom line: A major update to our favorite Windows 8 hybrid, the IdeaPad Yoga 2 Pro is still a better laptop than tablet, but the new version adds a future-proof better-than-HD display at a great price.                                                                                                                                                                                Specifications

The multitouch trackpad is still the industry's best, and even better, the 13-inch MacBook Air now starts at $100 less than the previous model.                                                                                                                                                
Performance:
The new Haswell processors use very little power, giving the 2013 13-inch MacBook Air and absolutely stunning battery life. In our test, in which we streamed the live BBC News channel feed on iPlayer over a wireless network, the laptop lasted for nine hours. That's significantly better than the 11-inch MacBook Air's 7 hours 15 minutes, and a substantial improvement over the 2012 MacBook Air's 5.5 hours.
Since switching to solid state storage off the shelf with the late 2010 update, the MacBook Air has been known for its good battery life. But with the Haswell processors in place, it's absolutely stunning. At last, you can use your notebook all day long on a single charge.
But, Newer features such as touch screens and higher-resolution displays are still missing. The ultrabook competition is catching up, in terms of design.
The bottom line: Apple keeps the latest MacBook Air updates on the inside, but greatly improved battery life and a lower starting price make up for a lack of flashy design changes.                                                                                                                                                                                                                               Specifications

HP Envy x2 vs Acer Iconia W510 vs Dell XPS 12:Which is better?

W.A.Khan,                                                                                                                                                                                                                                                                                                                 HP Envy x2                                                                                                                                             The HP Envy x2 has a clean, comfortable design and feels lightweight in tablet form. It has excellent battery life, and works just as well as a laptop as it does as a tablet.
But, The laptop mode is top-heavy, and the awkward tablet detachment mechanism isn’t perfect; it has limited ports; and a slower Atom processor means in performance it's far behind most ultrabooks, even though it’s priced like one.
The bottom line: The HP Envy x2’s capacity to be a full Windows 8 tablet or dock with a keyboard works as well as advertised, provided you’re willing to live with slower performance at a high price. You’re paying for style.

Battery life is excellent.
But, In laptop mode, the system is awkwardly top-heavy, and the puny keyboard and touch pad are not designed for serious use.
The bottom line: Offering low-powered Intel Atom tablet/laptop hybrids for $750 or more is a dodgy proposition for budget-looking systems such as the Iconia W510, but all-day battery life is a great selling point.

But, For all the hype about touch and tablets with Windows 8, the XPS 12 still works better as a laptop than as a slate. Its battery life is on the low side.
The bottom line: Dell has revamped its rotating Duo laptop concept into the much-improved XPS 12, but like most convertibles, it makes a better laptop than tablet.

Sony Xperia Z2 Tablet vs Apple iPad Air vs Nokia Lumia 2520:Hot Cake Is...........................

W.A.Khan,                                                                                                                                             Sony Xperia Z2 Tablet                                                                                                                             Sony's previous Xperia Tablet Z was an incredibly slender piece of kit, measuring only 6.9mm thick, but the new model has managed to slice off even more, coming in at only 6.4mm. Its slimness is immediately noticeable when you pick the slate up as it feels like a thin pamphlet. At 426g it's very light as well, which should help make it comfortable to use for longer periods.Design-wise, not much has changed since the previous model. The front is a button-free, all glass design, while the back panel is a wide expanse of matte black plastic, with the minimal Sony branding in the middle. Like its predecessor, the Z2 Tablet is completely waterproof, allowing it to shrug off an errant spilled drink or let you dunk it in the sink to rinse off smeary fingerprint marks.The 10.1-inch display boasts a Full HD resolution, making it well equipped to tackle glossy, high definition shows on Netflix. It's not quite matching the iPad Air's whopping 2048x1536-pixel resolution, although side-by-side, I doubt you'd notice much difference.On the back of the tablet is an 8-megapixel camera which should be at least good enough for some Instagram shots of whatever you've cooked that evening.Stuffed into that skinny frame is a quad-core Qualcomm Snapdragon 801 processor, clocked at an impressive 2.3GHz, backed up by 3GB of RAM.                                                        Specifications

The new iPad slots right in where its predecessor left off, priced at $499 for a lowly 16GB, $599 for 32GB, $699 for 64GB, and $799 for the maximum 128GB configuration. The iPad Air delivers more performance and comparable battery life in an attractive and impossibly thin-and-light package. An improved front-facing camera makes FaceTiming look better, and the Retina Display still looks great.
But, The Touch ID fingerprint scanner, introduced on the iPhone 5S, is sadly absent here, meaning you’ll still have to type in a passcode with every unlock and a password with every purchase. Starting at $499 for 16GB, it’s still expensive compared with the competition.                                                                             Performance:                                                                                                                                             The iPad Air shares the same processor with Apple’s flagship phone, albeit with a slight bump in clock speed. While the 5S runs at 1.3GHz the Air runs at 1.39GHz. It can achieve this because of the increased space and improved heat dissipation of the Air compared to the much smaller iPhone 5S.
Indeed, before we go into the detail about performance it’s worth noting that the iPad Air manages to keep its cool with consummate ease. Even when running intensive 3D games and apps for hours it barely breaks a sweat and, therefore, neither do your hands.
In practice, the iPad Air is blisteringly fast. Apps open instantly and games like Infinity Blade 3 look sumptuous and run smoothly. The benefits of having a SoC means that the GPU can be used to tackle compute tasks, which makes video editing and compute intensive apps, like AutoCAD, show no hint of slowdown.
The iPad Air performs 59% faster than the iPad 4 in the 3D Mark Ice Storm Unlimited CPU and GPU test and 91% faster in Geekbench 3 tests. The Peacekeeper browser test, which assesses web browsing performance, shows that the Air trounces its predecessor by being more than twice as fast. It's also faster than the stonking Snapdragon 800 processor on the likes of the Sony Xperia Z Ultra and Google Nexus 5. We're talking matter of degrees here, but the difference is there all the same.
Battery life:                                                                                                                                                   Battery life on the iPad Air is quoted at "Up to 10 hours of surfing the web on Wi-Fi, watching video, or listening to music". We would say that's actually not a bad estimate, although the drain was closer to 2% every 10 minutes in general use, which equates to around nine hours' use.
Standby time is much, much better though. We found that we could stick the iPad Air in a bag, taking it out for the commute and messing about with on the sofa at home, for at least three days before it began to get low on battery.
In fact, the only real task that killed it was connecting to our amplifier via Wi-Fi while simultaneously streaming music to the same device through Bluetooth. It's doing things like this that make you realise that this is the kind of thing that we envisaged at the turn of the century, a tablet that has the brains and connectivity to do all the tasks we could want.In terms of connectivity, we've already mentioned the excellent Wi-Fi performance (in terms of distance from router, rather than improved speed) through the Multiple In, Multiple Out (MIMO) technology.
4G bands are now covered throughout the globe, and low power Bluetooth is also on board as well, making it an incredibly well-connected device.
The bottom line: Functionally, the iPad Air is nearly identical to last year’s model, offering only faster performance and better video chatting. But factor in design and aesthetics, and the iPad Air is on another planet. It’s the best full-size consumer tablet on the market.                                                                        Specifications

The Finnish manufacturer’s first tablet, a direct competitor to Microsoft’s Surface 2, has a big trick up its sleeve: it’s only available with built-in LTE, which isn’t even yet an option on the Surface line. It’s available from Verizon and AT&T now, starting at $399 with a data-plan agreement. The 2520 is designed to be completely and entirely mobile, a tablet you bring everywhere and do everything with.The Nokia Lumia 2520 features fast gaming performance and LTE support out of the box. Xbox Music is an incredibly robust streaming app, and Nokia Music allows you to listen to songs you don't own without an Internet connection. It includes the full version of Office.There's an 8,120mAh battery inside the 2520, which Nokia reckons will give an impressive 25 days of standby time. It put up a good fight in general use too. I was easily able to get a day of mixed use from the slate and if you're more cautious, you can eke it out over a few days.At 1920 x 1080 pixels, the Lumia 2520’s LCD screen is gorgeous and gets plenty bright. Gorilla Glass 2 covers it so the 2520 can withstand some light abuse. On the inside is a top-notch ARM tablet. It runs on Qualcomm’s industry-leading Snapdragon 800 quad-core processor, running at 2.2GHz. 2GB of RAM, a MicroSD card slot capable of holding a 64GB card, and 32GB of internal file storage are included.
But, It's thicker and heavier than recent tablets, and its pointy corners are distracting. The screen has a yellow tint, storage expansion is only accessible with a key or paperclip, and the keyboard accessory isn't as comfortable to type on as the Surface 2's.
The bottom line: Unless you want a Windows RT tablet with cellular connection, skip the Lumia 2520 and get the Surface 2 instead.                                                                                                             Specifications

HP Envy Rove 20 vs Lenovo IdeaCentre Horizon 27 vs Dell XPS 18:Who is the winner?

W.A.Khan,                                                                                                                                                                                                                                                                                                                   HP Envy Rove 20                                                                                                                                   The 20-inch screen is an LED-backlit IPS display, and looks great, with bright colors and good off-axis viewing. It's covered by edge-to-edge glass that extends across the thick black screen bezel, and touch is, as on nearly every Windows 8 machine to date, very responsive.The HP Envy Rove 20 costs a bit less than some other tabletop PCs, includes great audio, and runs long enough to watch a couple of movies without being plugged in.
But, It's heavier than some comparable big-screen systems, uses a lower-end CPU, and the 20-inch display isn't full HD.
The bottom line: HP's entry in the growing tabletop PC field, the 20-inch Envy Rove 20, is a fun family PC, but it really should have a full 1080p display.                                                                                             Specifications                                                                                                                                           Display size/resolution 20-inch, 1,600x 900 touch screen                                                                         PC CPU 1.7GHz Intel Core i3-4010U                                                                                                     PC Memory 4GB 1,600MHz DDR3 SDRAM                                                                                         Graphics 32MB Intel HD Graphics 4000                                                                                                   Storage 1TB, SSHD hard drive                                                                                                                   Optical drive None                                                                                                                                     Networking Gigabit Ethernet, 802.11b/g/n wireless, Bluetooth 4.0                                                            Operating system Windows 8 (64-bit)

It includes several gaming accessories and has a custom user interface, Aura.
But, The heavy, clunky kickstand can get in the way, there's a little sluggishness with some of the software, and battery life is way too short for a game of Monopoly.
The bottom line: Tabletop PCs may not be fully ready for the mainstream, but this coffee-table-size version from Lenovo is fun to use, and doubles as a solid all-in-one desktop.                                                         Specifications                                                                                                                                             Display size/pixel resolution    27-inch, 1,920x1,080 touch screen                                                             PC CPU     1.8GHz Intel Core i5-3427U                                                                                                 PC memory    8GB 1,600MHZ DDR3 SDRAM                                                                                    Graphics        2GB Nvidia GeForce GT620M                                                                                            Storage         1TB, 5,400rpm hard drive                                                                                                   Optical drive       None                                                                                                                              Networking         Gigabit Ethernet, 802.11b/g/n wireless, Bluetooth 4.0                                                   Operating system          Windows 8 (64-bit)                                                                                           Price;$1,699                                                                                                                                            VS                                                                                                                                                           Dell XPS 18                                                                                                                                               The Dell XPS 18 is one of emerging new category of PC. It's an all-in-one Windows 8 machine which sits on a heavy metal stand and comes with a wireless keyboard and mouse. The Dell XPS 18 combines an all-in-one PC with a lightweight 18-inch tablet, making it a flexible system for at-home entertainment and productivity.
But, You're paying a premium for a relatively small screen. Less expensive configurations cut too many corners to be a good deal.
The bottom line: It's the best of the small handful of current tablet/all-in-one hybrids, with a subtle, sophisticated design and good battery life, but this new genre is still in its early days.                                   Specifications                                                                                                                                           Display size/pixel resolution 18-inch, 1,920x1,080 touch screen                                                                PC CPU 1.8GHz Intel Core i5-3337U                                                                                                   PC memory 8GB 1,600MHZ DDR3 SDRAM                                                                                         Graphics 32MB Intel HD Graphics 4000                                                                                                   Storage 1TB, 7,200rpm hard drive                                                                                                             Optical drive None                                                                                                                                  Networking Gigabit Ethernet, 802.11b/g/n wireless, Bluetooth 4.0                                                           Operating system Windows 8 Pro (64-bit)                                                                                                 Price $1,349.99

Lenovo ThinkPad X1 Carbon vs HP EliteBook Folio 9470m vs Sony Vaio Duo 11:Who is the best?

But, For such an expensive laptop, battery life is just so-so. Consumer-friendly options such as HDMI are missing.
The bottom line: The business-oriented Lenovo ThinkPad X1 has a few quirks, but is otherwise a very impressive business-oriented ultrabook with strong crossover potential.

But, There's no touch screen, it has a non-high-res display, and there's a general lack of unique features to justify its high price.
The bottom line: The HP Elitebook Folio 9470m does a serviceable job at being a good thin all-around Windows 8 business laptop, but it doesn’t rise from the pack, and it doesn’t take any chances.

But, The Duo's design misses the mark for use as a tablet and a laptop, feeling like too much of a compromise.
The bottom line: While there are certainly things to like about the Sony Vaio Duo 11, the design gets in the way of enjoying them.

Lenovo IdeaPad Yoga 11S vs Microsoft Surface Pro vs Acer Iconia W510:Which is better?

Light enough to travel easily, and so small it can tuck in any bag with ease.The Lenovo IdeaPad Yoga 11S is a great 11-inch ultraportable touch-screen laptop that also has a flip-around display for tablet and hybrid use.
But, Recent 11-inch laptops from Apple and Sony have raised the bar for ultraportables, especially when it comes to battery life. The Yoga 11S needs an upgrade to Intel's latest processors.
The bottom line: Like the larger 13-inch model, the 11-inch Lenovo IdeaPad Yoga 11S is a useful hybrid that doesn't forget it's a laptop first, but it's stuck with what feels like old hardware for now.                         Specifications

As a hybrid PC it's an undeniable compromise - but that's no bad thing.               The Microsoft Surface Pro fits a full ultrabook experience in a compact 10-inch tablet. Thanks to the ingenious Type and Touch covers, it offers a comfortable interface and typing experience. The clean, crisp design and sharp 1080p screen rise above the competition.
But, The battery life is disappointing, and more ports would be nice. The 64GB model barely has any free storage. It costs as much as a regular laptop, especially because the cool keyboard cover isn't included by default.
The bottom line: The Surface Pro's gutsy design successfully reinvents the Windows 8 laptop by cramming an ultrabook experience into the body of a 10-inch tablet. Those wanting to go all-in on the tablet experience won't regret buying the Surface Pro, but we're holding out for a future, more polished generation of the device.

Battery life is excellent.
But, In laptop mode, the system is awkwardly top-heavy, and the puny keyboard and touch pad are not designed for serious use.
The bottom line: Offering low-powered Intel Atom tablet/laptop hybrids for $750 or more is a dodgy proposition for budget-looking systems such as the Iconia W510, but all-day battery life is a great selling point.

Lenovo IdeaPad Yoga 11S vs Acer Aspire P3 vs HP Envy x2:Who is the winner?

W.A.Khan,                                                                                                                                                                                                                                                                                                                   Lenovo IdeaPad Yoga 11S                                                                                                                       Functional and flexible, the Lenovo Yoga 11S looks to be just what we want in an ultrabook. Light enough to travel easily, and so small it can tuck in any bag with ease.The Lenovo IdeaPad Yoga 11S is a great 11-inch ultraportable touch-screen laptop that also has a flip-around display for tablet and hybrid use.
But, Recent 11-inch laptops from Apple and Sony have raised the bar for ultraportables, especially when it comes to battery life. The Yoga 11S needs an upgrade to Intel's latest processors.
The bottom line: Like the larger 13-inch model, the 11-inch Lenovo IdeaPad Yoga 11S is a useful hybrid that doesn't forget it's a laptop first, but it's stuck with what feels like old hardware for now.                         Specifications

All the hardware and clever stuff can be found in the 19.75 mm thin slate itself.The Acer Aspire P3 is a solidly built, full Core i5 Windows 8 tablet with its own keyboard for under $1,000. The lower-res display at least looks crisp.
But, Generic design, a cheap-feeling keyboard case, last-gen Intel processors.
The bottom line: Yet another Windows 8 Core i5 tablet, the Acer Aspire P3 has only one thing in its favor: it costs a maximum of $899.                                                                                                                      Specifications

Its outstanding industrial design really shows the potential of a tablet/laptop hybrid. The HP Envy x2 has a clean, comfortable design and feels lightweight in tablet form. It has excellent battery life, and works just as well as a laptop as it does as a tablet.
But, The laptop mode is top-heavy, and the awkward tablet detachment mechanism isn’t perfect; it has limited ports; and a slower Atom processor means in performance it's far behind most ultrabooks, even though it’s priced like one.
The bottom line: The HP Envy x2’s capacity to be a full Windows 8 tablet or dock with a keyboard works as well as advertised, provided you’re willing to live with slower performance at a high price. You’re paying for style.
