Xoom is just a wanna be iPad, based on Andriod. Nothing revolutionary. Plain old touch screen and uses a common OS shared by other tablets. Only does 720P HD Recording. No HDMI. PlayBook on the other hand is really different from the core, and tablet optimized, built from scratch. It runs a custom built powerful QNX OS. Main advantage: Has touch sensitive bezel to fast switch between apps: Horizontal bezel swipe from left or right: switch to next or previous apps. Bottom bezel swipe up: View all open apps. 3 MP + 5 MP + 1080 P Video recording and HDMI out. 1 GB RAM. 1 GHZ Dual core processor. And, Runs Flash 10.1! We've got a winner.
