Motorola has put together a very handy comparison tool/chart for the three versions of the upcoming XOOM tablet. Three? Yep, there are GSM, CDMA, and WiFi flavors to choose from although the radio is the only difference we can spot between them. Still, if you’re a spec junkie or want to know about every little codec and media format supported, this is your type of chart. Who knew there were so many Bluetooth profiles?
