Played with the Xoom over the weekend at an event in Dallas, it's a pretty cool device but while it is new tech, I think the Tab has an upperhand in price, portability and flexibility. I love my Tab, it fits in my pocket and I can take it anywhere. You can buy one on any carrier you desire. And I purchased it new on Craigslist for $400, half the price of the Mot Xoom. Really I had it in my pocket with me during the Superbowl, you can't do that with a 10in screen. Made it a perfect travel mate to watch movies on the flight home without requiring space in my bag for travel.
I won't give this sucker up, it may not be the most current tech but come on, it was released 4 months ago...and does everything it should and better than most devices on the market. Plus all the tablet apps will work with the Tab, who needs to upgrade?!
