Lenovo IdeaPad K1 The IdeaPad K1 is one of two tablets from Lenovo, each with the same processing guts and the same size of displays, but with very different physical designs.Lenovo's IdeaPad K1 packs in all of the best features found in today's modern Honeycomb tablets (upgradeable to Android 4.0) and offers some unique Android optimizations and preloaded apps.The Lenovo IdeaPad K1 does have good specs. Tegra 2 should provide plenty of power, the 32GB of on-board storage is great and it's got a big, high-res screen. For under $500, that's not bad value for money.
But, The design is thick and heavy compared with the latest from Apple and Samsung, not all of the Android tweaks pay off, and the screen isn't as bright as it could be.
The bottom line: Lenovo plays it safe with the IdeaPad K1, delivering a solid tablet that does little to stand out from the Honeycomb herd. Specifications

Weight1.6 lbs Price;$499.99 VS Apple iPad 2 The iPad 2 is a well-balanced combination of sleek, inspiring design and a high-end collection of premium specs that are tied together through an unrivalled user interface and ease of use that ensures the product is open up to tablet novices and gadget aficionados alike.Apple's iPad 2 is dramatically thinner and boasts front and rear cameras, FaceTime video chat, a faster processor, and 3G options for both AT&T and Verizon.The iPad 2 managed an astonishing 10 hours and 26 minutes of non-stop playback. That beats Apple's own claims, and bests its nearest competitor -- the Xoom -- by about 2 hours.
But, The iPad's screen resolution hasn't budged, photo quality is mediocre, there's still no Adobe Flash support, and ports for HDMI, USB, and SD all require adapters.
The bottom line: The iPad 2 refines an already excellent product. Its easy-to-use interface, vast app catalog, and marathon battery life bolster Apple's claim to being the king of tablets. Specifications

Weight21.2 oz Price;$399.00 VS Sony Xperia Tablet S The Sony Xperia Tablet S has a comfortable, high-quality design, a sharp-looking screen, storage expansion, and potential as a universal remote alternative.Nvidia's Tegra 3 processor is inside most of the tablets I've tested in the last six months, and they pretty much all work the same. The Xperia Tablet S is fast and responsive, and is particularly adept for playing games — I'm getting really good at Shadowgun as I test more and more tablets, and it's as smooth and impressive on the Xperia Tablet's display as any I've tried.With a 6,000mAh battery, the Sony Xperia Tablet S doesn’t have a huge battery. However, as its screen is so relatively low-tech, it doesn’t really need much more. Set to play video, the tablet’s battery will last in excess of eight hours, which is decent enough for a tablet of this size.
But, Unfortunately Wi-Fi currently shuts off whenever the tablet sleeps, waking the tablet from sleep takes way too long, and its screen flickers intermittently. Price is a bit high for what's offered.
The bottom line: The Xperia Tablet S has an excellent design, but there are cheaper alternatives that provide similar and better tablet experiences. Specifications
