What's the difference between a WiFi-only Xoom tablet and one equipped with EV-DO Rev. A or HSPA bands? Just $200 and the radio chip within. Motorola just released the full spec sheets for its full lineup of Android Honeycomb tablets, and they're otherwise exactly the same inside. That goes for the Tegra 2 SOC, of course, but also surprisingly the GPS, which is often baked right into the cellular radio in mobile devices like these. Good on Motorola for keeping the functionality in!
