I have the WiFi only Xoom which I bought at Costco almost four months ago. I love it but have been wondering about the differences between the WiFi only and the 3g versions. The back of my WiFi Xoom has a top section which is black in color and seems to have a rubberized coating. The lower part of the back seems like brushed aluminum and does not have the rubberized coating. Is the back of the 3g version different?
