Apple iPad 4 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

The tablet feels strong and well-built, runs Office 2013, and includes rich video and music services. Its keyboard cover accessories are the best ways to type on a tablet, period.
But, The tablet's performance can be sluggish, its Windows Store is a ghost town, Metro takes getting used to, and the Desktop interface feels clunky and useless.
The bottom line: If you're an early adopter willing to forget everything you know about navigating a computer, the Surface tablet could replace your laptop. Everyone else: wait for more apps. Specifications
