There truly is no way to say which is the best, there were so many revealed at the CES. The most popular ones you have heard of are of course the Blackberry Playbook and the Motorola Xoom. But there were some others introduced as well that I feel are worth mentioning. Notion Ink introduced the Adam thinkpad which looks to be pretty promising, as well as Lenovo as made some interesting tablet/PC's you can disconnect the tablet from essentially a shell based PC, this tablet has full laptop capability. If I think of anymore worth mentioning I'll try to answer be sure to check on my hubs from time to time as I will be writing mini reviews on what I can find as far as tablets are concerned. Hope this helps.
