Verizon may have a response to criticisms that it priced the Motorola Xoom out of contention with the iPad 2 if an internal leak pans out. A listing in the carrier's device manager shows a 16GB version of the Xoom. It doesn't have any apparent differences in the Droid-Life sighting and would still be upgradable to LTE-based 4G whenever Motorola is ready to offer the part swap.
