What absence of WiFi? Only thing close to that I have read is that they want you to pay for a month of cell to setup the WiFi, Specs certainly indicate WiFi.
Find this hard to believe. I would suppose I could buy a XOOM outright, not involving a carrier. If you can't, this is going to be quite the fail.
Part of the pricing magic is comparing the wrong stuff. The XOOM is a 32G, Wi-Fi 2.4GHz & 5GHz 802.11b/g/n, 3G, 4G LTE upgradeable, w/Personal Hotspot device. The nearest iPad, 32G iPad with Wi-Fi + 3G is $729. Not that far from $800. Up to the user if the Xoom has sufficient additional features to make up the difference, such as HDMI out, microSD slot, USB, etc.
