Lenovo IdeaPad Yoga 13 vs Microsoft Surface Pro 2 vs Acer Iconia W700:Who is the winner?

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

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

With an Intel Core i5-3317U at the helm, along with 4GB of DDR3 SDRAM, Intel HD 4000 graphics and a 128GB solid state drive, the Iconia W700 can give laptops a run for their money when it comes to speed. It had no problems streaming video from the Web (from paid services such as NBA.TV, as well as YouTube and Vimeo), and it was responsive when it came to browsing Web pages, loading apps and flicking through photos. It really is perfect for media consumption.Acer claims the Acer Iconia W700 battery (4,850mAh capacity) battery lasts eight hours. This is a little optimistic. We found it was closer to six hours during normal, everyday use. Were it a laptop that would be ok, but it's not great for a tablet and unlike most tablets it has a proper dedicated charger - it doesn't charge via USB.
But, The non-adjustable stand limits viewing angles, and you'll need an external mouse or touch pad for efficient Windows navigation.
The bottom line: One of the only Core i5 slate-style Windows 8 systems we've seen, the Acer Iconia W700 asks few compromises for full-time use, but the design isn't for everyone.                                                                                                                                                                                                                       Specifications
