It looks like Dell incorporated some major changes and fixes to this new tablet PC. Unfortunately, the price is still way too high. However, for those who are able to afford such luxuries, the Latitude XT2 is a really nice convertible tablet. I'll stick with my Thinkpad X200 tablet for now. I really like the Thinkpad keyboard and the form factor.
I'm still waiting for the day when someone makes a really thin convertible tablet (by thin I mean Apple MacBook Air thin). Maybe a really thin MacTablet or iTablet will emerge this year. If that happens, then I may need to get ready to use OS X (unless I run BootCamp, Parallels Desktop for Mac, or VMware Fusion).
