Anyone purchased one of the 3g tablets with a data plan? Preferably from Verizon. How much data do you use? I am thinking about getting one for my son (6 years old) as he uses my phone every time we go somewhere and my phone is always dead. Right now I can get one of them for $199 with a two year contract. Since he really enjoys computers (not just games) and MP3 (just started) I was originally thinking an iPod but this is about the same amount of money and can do so much more. I have a Droid Incredible but the thought of a tablet is intriguing.
