Has anyone played with the idea of switching from a phone to a tablet and using a bluetooth or nfc headset? I figure the only time I talk is with a headset, and I would like a eReader and tablet already. Figure, just combine all three with a tablet, put a dialer app on an android tablet compatible with Sprints network plan. I'm on Sprint, and if there are any tablet recommendations I can use on their network, please tell me. Their selection is a bit too expensive.
