This is something that has peaked my interests, using a tab as a "all-in-one" device. If you had a Google voice/talk account, couldn't you make/receive calls as long as your logged into your gmail account and get voice via a BT headset or speaker phone? Get unlimited text messages and make unlimited calls to cell and lan lines. Couldn't you also turn off the Sprint Data connection when at home and use WIFI to try to offset the 5GB data cap? If a lot of people start to use this, wouldn't we be able to push Sprint in the direction of offering an unlimited plan for the tabs?? I hate the idea of holding a 5x7 picture frame to my head as a phone but using cell companies as just a data connection and getting free everything sounds like a good path to go down!
