Yes situations change, so a 3G xoom will also work on Wi-Fi, correct? If down the road I decided to purchase an additional data plan then the xoom could be used as a stand alone (w/o the need of being paired to the Bionic). Can the xoom be hard tethered to the Bionic for a more successful pairing than the bluetooth?
Yes, a 3G/4G Xoom has WiFi and can be used as a standalone device on the Verizon network or with a 3G/4G phone through WiFi. The downside of using the Xoom as a standalone mobile broadband device is that there are no unlimited plans available for the Xoom. My 4G Bionic, on the other hand, has an unlimited plan that costs me $24 a month plus the hotspot, which costs $24 a month. This means that for $48 a month, I have an unlimited plan that I can share with both of my Xooms, all of my laptops, and anything else I want to tether to it.
I do like the fact that I can make it a standalone 3G/4G device down the the road, if I choose to do so though.
