The Five Coolest Tablet PCs Of 2011

1. Apple iPad 2

When it comes to tablets, Apple is still king of the hill. The company introduced its second-generation iPad this year, and it's an upgrade from the original iPad in just about every way. The iPad 2 comes with a new chip, the dual core A5 chip based on ARM's Cortex-A9 architecture, which Apple says is twice as powerful as the previous chip and can be adjusted to save battery life.

The iPad 2 also doubled the RAM (512 MB) of the original iPad, adds two Webcams, and features a thinner and lighter case. And it still has the sturdy, user-friendly Apple iOS and a tremendous ecosystem of mobile apps. The iPad 2 starts at $499.
