Asus Taichi 21 vs Lenovo IdeaPad Yoga 11S vs Asus Taichi 31:Who is the winner?

 W.A.Khan,                                                                                                                                                  Asus Taichi 21                                                                                                                                           The Asus Taichi 21 offers a clever implementation of a dual-screen design in a slim Core i7 chassis.It features dual 11.6" IPS displays with 16:9 aspect ratios and Full HD 1920 x 1080 native resolutions, thanks to the integrated Intel HD Graphics 4000. 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

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

The Taichi can behave like a regular Ultrabook and even doubles up as a tablet when closed thanks to the secondary display on the top.The Asus Taichi 31 sports two Full HD IPS screens. The manufacturer wants to attract both target groups with the Taichi 31 and designs a convertible device that is an ultrabook and tablet in one. Unlike competing products like Dell's XPS 12 Convertible or Lenovo's IdeaPad Yoga 13, the Taichi 31 does not use twisting mechanisms, such as a flip or fold hinge. It installs a second, back-to-back screen in the ultrabook's lid.An IPS screen with a Full HD resolution of 1920x1080 pixels is used for both the inner screen and the one built into the lid, i.e. outer screen. Only the screens' finish differs. The laptop's screen features a matte coating and the tablet-typical outer screen features a glossy edge-to-edge design.The body is primarily made of aluminium with a dark, almost graphite-like colour and brushed finish. The edges of the palm rest are tapering, and while they do look good, they are quite sharp and not too gentle on your wrists. The laptop weighs a little over 1.5 kg, which is normal for a laptop its size, but heavy for a tablet. The build quality is top-notch.There will be two Asus Taichi models, the 11.6-inch, 1.25kg Taichi 21 and the 13.3-inch, 1.55kg Taichi 31.Many laptop manufacturers are still holding on to the aging TN panels with just 1366x768 resolution, but ASUS used two Full HD IPS panels for the Taichi. They're not identical, as the one on the inside does not have the touch layer the one on the outside has. So when you fold down the screens, you basically have a large, thick tablet. Flip it up, and you have an Ultrabook. The screen on the outside with the touch layer also is more glossy than the one on the inside, the 'laptop' screen.With both the 11.6-inch Taichi 21 and the 13.3-inch Taichi 31 you get a choice of Intel Core i5-3317U or quad-core Core i7-3517U processors, backed by 4GB of RAM and a 128GB or 256GB SSD. Graphics are of course handled by Intel’s integrated HD 4000 chipset.Asus has given its most premium laptop/tablet a decent set of HD snappers, with a 720p one at the front (when in laptop mode) and a 5megapixel, 1080p rear shooter for the tablet.A battery backup time of 2 hour was registered in the Classic test, while the Reader's test result yielded 5 hours 45 minutes. In a real time usage that involved using office applications, surfing the internet, occasional music and video, and watching some YouTube clips, the battery lasted for over 8 hours 30 minutes. This is good battery backup for the Windows 8 Ultrabook with Full HD screen and an Intel Core i7 CPU.A completely new cdesign in convertible tablet / laptops.The unique Windows 8 device has back-to-back 13.3-inch screens and works as a touch-enabled laptop with lid open, or as a tablet with lid closed.Price:$1100 to $1300
