4. BlackBerry PlayBook
I was at the event last fall where RIM announced the BlackBerry PlayBook and my first impressions were not very good -- mostly because RIM kept it behind glass. However, after getting my hands on the final product, I was a lot more impressed. The PlayBook looks like it could become a factor in the tablet market, especially for businesses that are already invested and committed to the BES backend infrastructure. This is a 7-inch tablet, so that limits its appeal a bit -- except for the vocal minority who like the smaller form factor. Still, the hardware feels great, the tablet OS is easy to figure out, and the performance is staggeringly good. BlackBerry die-hards alone could turn this one into a winner. It's also the best tablet for Web browsing because of its excellent implementation of Flash.
