Apple iPad 4 vs Asus Transformer Pad Infinity TF700 vs Sony Xperia Tablet S ;Who is fit for use?

W.A.Khan,                                                                                                                                                   4/5/2013,                                                                                                                                                                                                 Apple iPad 4                                                                                                                                                                                  The new iPad with Retina Display is the best large tablet going with better battery life and performance than both the iPad 3 and the other large tablet competition.The newest iPad's faster A6X processor adds extra system speed and graphics power. Improved worldwide cellular compatibility makes the LTE model a more appealing proposition. And the iOS App Store remains best in class, with the widest selection.
But, The fourth-gen iPad is otherwise identical to its recent predecessor -- same size, weight, and Retina screen. It's heavy to hold in one hand, and most older accessories won't work without investing in a pricey Lightning adapter.
The bottom line: The latest iPad adds several tweaks and improvements to secure its position at the top of the tablet heap. It's better all around, but third-gen owners need not apply.                                                                                                                     Specifications

Also, apps launch quickly, GPS works well, and its rear camera is the best I've seen on any Android tablet. The tablet's body has the same great thin and light design as the Prime.
But, So far, not enough Android apps take advantage of the TF700's higher pixel count. Also, its battery life isn't as good as the Prime's.
The bottom line: The Asus Transformer Pad Infinity TF700 is one of the fastest Android tablets out there, combining an already proven design with a better camera, a faster processor, and a beautiful screen.                                                                               Specifications

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
