Microsoft Surface Pro 2 vs Lenovo IdeaPad Yoga 11S vs HP Envy x2:Hot Cake Is.............

W.A.Khan,                                                                                                                                             Microsoft Surface Pro 2                                                                                                                               The Surface Pro 2's display may not have received an upgrade, but then it didn't need one. It's still a fine IPS panel that helps bring Windows 8.1's colorful and vibrant nature to life. The tablet itself is easier to use thanks to improved keyboard covers - even the Touch Cover 2 will prove more than adequate for most this time around.The Microsoft Surface Pro 2 is a faster, longer-battery-life version of the original model, upgraded with a current-gen Haswell processor. The keyboard cover is also improved with backlit keys, and is among the best tablet accessories ever devised.The Surface Pro 2 is a very tough product to judge, which is what makes it interesting. The good news is Microsoft has sorted out the most serious issue with the first version: the battery life. At around eight hours, the Surface Pro 2 mixes it with the Ultrabooks like the Samsung Ativ Book 9 Plus and Sony VAIO Pro 13, even if it still falls a little short of 'tablet class' battery life.
But, The Surface Pro 2 remains stubbornly thick and heavy compared with some sleeker competitors. The base 64GB version may leave you starved for storage, and the keyboard cover, practically required, should be included instead of sold separately.
The bottom line: Microsoft's subtly updated Windows 8.1 tablet feels more like Surface Pro 1.5 -- improved battery life and better accessories make it a worthwhile (albeit pricey) laptop replacement, but it's still not an iPad-level category killer.                                                                                                                             Specifications

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

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.                                                            Performance:                                                                                                                                               Unfortunately, as soon as we start talking performance we’re confronted by the fact that Clover Trail is still Atom, and Atom is still not in any way, shape or form a performance chip – and that 2GB RAM maximum doesn’t help here either.Don’t get us wrong, for navigating through Windows and average daily use such as browsing the web and running apps or light programs, the Z2760 in the HP Envy x2 runs smooth as butter. Performance is consistently superior to that in the netbooks of yore, especially when it comes to HD video playback and light multi-tasking, and most non 3D-gaming apps you’ll find in the Windows store should run without a hitch.
However, proper multi-tasking; running intensive HD video simultaneously with another program; or using demanding programs like an image editor can still quite easily bring this kind of machine to its knees. In other words, as a tablet the x2 performs admirably, but as a laptop replacement you have to be prepared to put up with its limitations.
3D gaming in anything but the most casual titles, meanwhile, is also a big no-no. Even at minimum settings our test games simply refused to run or crashed after getting through the menus. Mind you, this is not surprising given that Intel’s integrated GMA 3600 chip paired with the Atom Z2760 is derived from an old PowerVR design the benefits of which Windows drivers don’t fully bring out. Hopefully updated drivers will eek out more performance.                                                                                                                            Battery life:                                                                                                                                                Battery life is impressive, living up to HP’s claim of seven hours when we streamed video from BBC iPlayer. And, of course, there’s a second battery in the keyboard, which provides an additional seven hours of battery life. No ultrabook that weighs a similar amount can claim to last this long.                                         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.

Lenovo ThinkPad Helix vs Asus Taichi 21 vs Sony Vaio Duo 11:Who is the Best?

W.A.Khan,                                                                                                                                                 Lenovo ThinkPad Helix                                                                                                                           The ThinkPad Helix is powered by a third generation Intel Ivy Bridge processor, up to Core i7 and up to 8GB of DDR3 1600MHz RAM. Aiding performance is an SSD of up to 256GB so its performance is top-notch. You’ll be able to choose between Windows 8 and Windows 8 Pro.The Lenovo ThinkPad Helix will be available in an array of spec configurations, but the one we saw  demonstrated was a mid-range example, with a Core i5 processor. Core i7 options will also be available. The ThinkPad Helix uses current Ivy Bridge-generation CULV Intel chips, backed-up by 8GB of RAM and a 256GB SSD. The screen and base are each under 2.0 pounds, but that's on the hefty side for an 11.6-inch system. That said, it's 20mm thin, qualifying for ultrabook status, and can run processors up to Intel's current-gen Core i7.Travel-friendly features include 3G/4G antenna options, NFC chip, and a spill-resistant keyboard.The Lenovo ThinkPad Helix feels like a hybrid roadwarrior. It's reasonably light, especially in its class, offers great build quality and careful attention to detail in its construction. It may not be a beauty, but it's one of the better full Windows 8 hybrid designs out there.                                                                                                                      Performance and battery life
A 1.8 GHz processor and 4GB of RAM may seem small on paper, but in practice the ThinkPad Helix is a surprisingly capable machine. Both the Windows 8 tiled interface and desktop ran smoothly on our review unit.
Browsing in either Chrome or Internet Explorer, we could get a dozen tabs going before performance started to chug. This is with the tablet docked in its helpful stand, which provides extra cooling and allows the processor to overclock a little.
The performance enhancement is noticeable, and the fans generate minimal noise. This is by no means a gaming machine, but we were able to play some Half Life 2: Episode 2 with an acceptable framerate.
The stand also provides additional battery life. With its help, we generally got 7 to 8 hours of web surfing and word processing. As just a tablet, the Helix got between 5 and 6 hours. That's not bad at all, certainly better than a Surface Pro, but one can't help but think of what Haswell could've done for this machine.

The main screen inside the lid is a normal laptop display while the outer lid features a secondary touchscreen display. Both screens can be used independently of each other so two people can use them at the same time.
But, Only one of the screens is touch-enabled, which feels like a major oversight. There are probably only a handful of situations where you'd need an outward-facing display.Tablet Mode is on par with this, lasting for 2 hours and 27 minutes. The Taichi is greedier in Dual-Screen Mode, lasting 1 hour and 48 minutes. That last score isn’t too bad considering both displays are on, and screens are one of the biggest battery hogs on a laptop.
The bottom line: More of a clever proof-of-concept than a practical product, the Asus Taichi still delivers on its basic promise, combining two displays for a unique take on the laptop/tablet/hybrid genre.                                                                                                                                                                                            Specifications

It’s certainly an attractive looking device, with an excellent high-definition, touchscreen. The Sony Vaio Duo 11 has a fine set of specs for an ultrabook and an excellent full-HD touch screen on which to take advantage of the Windows 8-style interface.
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.

LG G Pad 8.3 Google Play Edition vs Lenovo Yoga Tablet 8 vs Dell Venue 7:Which one is the Better one?

W.A.Khan,                                                                                                                                             LG G Pad 8.3 Google Play Edition                                                                                                             The LG G Pad 8.3 Google Play Edition features pure Android with a deeper Google Now integration, and receives the latest updates.It's the fastest Android tablet out there to date. It runs pure Android straight from Google and will likely be among the first to get future OS updates. The screen size is a nice compromise between portability and luxurious viewing space. The hardware is very solidly built. And in a refreshing change of pace, the speaker placement means they don't easily get blocked by your hands. Battery life is very good. It also has a sharp display, expandable memory, and runs a tad faster than its original LG counterpart.
But, The G Pad doesn't have the same elegant build-quality as Google's Nexus tablets, and this stock model lacks a few useful apps compared to the LG-skinned original.
The bottom line: Android purists will find Google's mid-sized LG G Pad 8.3 more compelling, but it's pricier than the model that's overlaid with LG's skin.                                                                                   Specifications

We were able to snap successive pictures without delay as apps like Chrome, Gallery, Flipboard and "N.O.V.A. 3" ran in the background.The Yoga’s 8-inch screen is a good size for gaming and reading books, but magazines, comics, and videos feel a tad cramped. Not that you’ll want to read much on the tablet anyways, as its 1280 by 800 resolution makes all content look fuzzy. Going to the Yoga after using the Nexus 7 or any of the retina display iPads made me feel like I needed glasses. It’s also only $250.
But, The tablet’s low-resolution screen is dull and the heavily modified operating system is downright ugly.
The bottom line: Though it feels well-built and has a handy kickstand, the Lenovo Yoga Tablet’s poor performance makes it hard to justify even at its low cost.                                                                     Specifications

It's lightweight, houses a microSD card expansion, and performs smoothly.The 7-inch IPS LCD brings the 1,280-by-800 resolution and front-facing camera of the Venue 8 to a slightly smaller panel, and it's slightly sharper as a result at 215 pixels per inch. It beats Asus's and Hisense's offerings. Amazon's Kindle Fire HD 7" has the same resolution, but has better color saturation and better viewing angles than the Venue 7. The Nook HD has a 1,440-by-900 display, beating both of these tablets in the high-res arms race.The Dell Venue 7 lasted for 6 hours and 20 minutes on the LAPTOP Battery Test (Web surfing via Wi-Fi), which is longer than the Sero 7 Pro (6:09), but an hour less than the 7:22 category average and more than three hours less than the MeMO Pad HD 7's epic battery life of 9 hours and 40 minutes.
But, Larger games take a while to load, the touch screen is sometimes unresponsive, and battery life only lasts about a day.
The bottom line: The Dell Venue 7 offers a simple design and smooth performance for the right price, but the Nexus 7 is a significant upgrade for not much more.                                                                         Specifications

It has excellent battery life, and works just as well as a laptop as it does as a tablet.                                                               Performance:                                                                                                                                               Unfortunately, as soon as we start talking performance we’re confronted by the fact that Clover Trail is still Atom, and Atom is still not in any way, shape or form a performance chip – and that 2GB RAM maximum doesn’t help here either.Don’t get us wrong, for navigating through Windows and average daily use such as browsing the web and running apps or light programs, the Z2760 in the HP Envy x2 runs smooth as butter. Performance is consistently superior to that in the netbooks of yore, especially when it comes to HD video playback and light multi-tasking, and most non 3D-gaming apps you’ll find in the Windows store should run without a hitch.
However, proper multi-tasking; running intensive HD video simultaneously with another program; or using demanding programs like an image editor can still quite easily bring this kind of machine to its knees. In other words, as a tablet the x2 performs admirably, but as a laptop replacement you have to be prepared to put up with its limitations.
3D gaming in anything but the most casual titles, meanwhile, is also a big no-no. Even at minimum settings our test games simply refused to run or crashed after getting through the menus. Mind you, this is not surprising given that Intel’s integrated GMA 3600 chip paired with the Atom Z2760 is derived from an old PowerVR design the benefits of which Windows drivers don’t fully bring out. Hopefully updated drivers will eek out more performance.                                                                                                                                   Battery life:                                                                                                                                                  Battery life is impressive, living up to HP’s claim of seven hours when we streamed video from BBC iPlayer. And, of course, there’s a second battery in the keyboard, which provides an additional seven hours of battery life. No ultrabook that weighs a similar amount can claim to last this long.                                        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.

Don’t expect to edit and render HD video in record time, for example.It’s a little light on storage too – almost 27GB of the 64GB solid-state storage is taken up by Windows itself, which only leaves you about 37GB for your own files. Fortunately, there’s a micro-SD slot that will allow you to add another 32GB storage if you need to.
The Atom processor also relies on the old Intel GMA integrated graphics, which means that your gaming activity will probably be restricted to casual games such as Angry Birds.The tablet gives you up to 8 hours battery life but you can double it to 16 hours when you connect it with the optional keyboard dock.
But, The keyboard has too much flex, and the docking hinge sticks. For only a little more, better products are available.
The bottom line: The IdeaTab Lynx is a perfectly functional Windows 8 hybrid but lacks the lower price of some competitors, or better design and features of others.

All the hardware and clever stuff can be found in the 19.75 mm thin slate itself.The Acer Aspire P3 has an 11.6-inch IPS touchscreen display. It’s not a full HD display, though, but 1,366 x 768 pixels.The P3 comes with a built-in Acer Crystal Eye HD front webcam captures video in 720p HD, bringing life to video web chats while the 5MP back camera captures photos in high resolution, which is more than enough for a hybrid device. The new Ultrabook features a 60GB or 120GB SSD for powering on the device and retrieving data quickly and securely.
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.The 5,280mAh battery will last for seven hours according to Acer.
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

Lenovo ThinkPad Twist vs Dell XPS 12 vs Asus Taichi 21:Who is the Best?

W.A.Khan,                                                                                                                                                Lenovo ThinkPad Twist                                                                                                                           The ThinkPad Twist has great Lenovo construction, a responsive touch screen, and a center hinge for flipping into tablet mode, all for a very reasonable price.The Twist has an uncommon size 12.5-inch screen, and at 1.6 kg is heavy for an Ultrabook of this size, let alone a tablet that usually weighs much less than half that.The ThinkPad Twist has a third-generation Intel Core i5-3317U processor, 4GB of RAM (3.82GB usable), and a 500GB HDD spinning at 7200rpm alongside a 24GB SSD caching drive. The Twist also has built-in Wi-Fi 802.11a/b/g/n, Bluetooth 4.0, and a slot for a SIM card, for users who want to be connected. But, The screen accelerometer can have a mind of its own, flipping into portrait view randomly. Battery life is merely OK, and the screen resolution is low for a modern laptop/tablet convertible.                                                                                                                                                                                                        The bottom line: Slightly less conservative-feeling than the average ThinkPad, the well-made ThinkPad Twist offers one of the better tablet modes from the first wave of Windows 8 convertibles.

Open the lid, and you can use the computer as you would any other notebook. You simply push the top front or bottom back of the display to pop it out of its frame, and then flip it over and close it to convert the machine into a tabletThe biggest improvement, though, lies in battery life. The Ivy Bridge version of the XPS 12 provided 5 hours of streaming video, but that figure rose to a 6 hours and 45 minutes when we tested again with the same test.The Dell XPS 12 is one of the most powerful Ultrabooks you'll find. It might be heavy and awkward as a tablet, but when you consider the value that's on offer, with the blistering processor, 8GB of RAM and 256GB SSD drive, there's more than meets the eye..
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.

The main screen inside the lid is a normal laptop display while the outer lid features a secondary touchscreen display. Both screens can be used independently of each other so two people can use them at the same time.
But, Only one of the screens is touch-enabled, which feels like a major oversight. There are probably only a handful of situations where you'd need an outward-facing display.Tablet Mode is on par with this, lasting for 2 hours and 27 minutes. The Taichi is greedier in Dual-Screen Mode, lasting 1 hour and 48 minutes. That last score isn’t too bad considering both displays are on, and screens are one of the biggest battery hogs on a laptop.
The bottom line: More of a clever proof-of-concept than a practical product, the Asus Taichi still delivers on its basic promise, combining two displays for a unique take on the laptop/tablet/hybrid genre.                                                                                                                                                                                          Specifications

Lenovo IdeaPad Yoga 13 vs HP Envy Spectre XT vs Apple MacBook Air:Which one is the Right Choice?

W.A.Khan,                                                                                                                                                 Lenovo IdeaPad Yoga 13                                                                                                                       The 13-inch Lenovo Yoga was one of the first convertible Windows 8 tablet/laptops.Packed into its flexible chassis, the Lenovo Yoga 13 has some tasty specs: its 13-inch IPS screen may not offer a Full HD (1,920 x 1,080) resolution, but at 1,600 x 900 pixels it’s significantly higher than many affordable rivals and offers 10-finger touch. Under the hood, this Yoga can offer up to a Core i7 CPU, up to 8GB of RAM and a 256GB SSD, putting it at the top of the convertible game in terms of power – yet Lenovo still claims battery life of up to eight hours. All that’s lacking is pressure-sensitive stylus support, but as the Core i7 version comes in at under  $1,000.00 , that’s easy to forgive.Intel's 1.70 GHz Core i5-3317U, which has two cores capable of delivering four processing threads with bursts up to 2.6GHz, outputs a surprising amount of giddy-up.Upgrading to the faster Core i7-3517U, which runs at 1.90GHz with bursts of up to 3.0GHz and has a 4MB cache vs. the Core i5-3317's 3MB cache, will give you even more CPU kick.The Lenovo IdeaPad Yoga 13 looks as good as any 13-inch ultrabook, with the added attraction of a 360-degree screen and a laptop body that can fold into a tent, stand, or slate.
But, Tablet mode leaves the keyboard exposed, and the Yoga 13 costs more than standard ultrabooks with similar components.
The bottom line: The Lenovo IdeaPad Yoga 13 is a convertible touch-screen laptop/tablet that most importantly doesn't compromise the traditional laptop experience.                                                               Specifications

You can expect a battery life of around 8 hours.
But, The design doesn't stand out as much as the original Spectre's did, and its battery life won't get you through an entire day. From a premium product, we'd expect a higher screen resolution.
The bottom line: A high-end laptop at a mainstream price, the HP Envy Spectre XT gets much of the look and feel right, with only a few missteps.                                                                                                        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

W.A.Khan,                                                                                                                                                 Lenovo IdeaPad Yoga 2 Pro                                                                                                                       The Lenovo IdeaPad Yoga 2 is an excellent ultrabook, even without digging into its hybrid capabilities. 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

But, The Envy TouchSmart 4 isn't very configurable, so you can't make it too much more powerful than it already is. It's on the heavy side for an "ultrabook" (if you consider 4.5 pounds heavy). Its touch pad is jumpy at default settings.
The bottom line: The HP Envy TouchSmart Ultrabook 4 is a good gateway to the Windows 8 experience with a responsive touch screen in a traditional laptop body.                                                                           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
