Does the extra $70 (when comparing the Xoom to the equivilently priced iPad) cover the 4G LTE upgrade?? Obviously LTE isn't up and running as it should be for devices and network side, but motorola was set on getting it out early, probably to get a jump on the rest of the tabs. Now, since a data plan is required for the 3G model, maybe this is to register each device on Verizons network so when the 4G LTE upgrade is available the process will be smoother.
