Seeing how much 3G capability increases tablet prices, I'm considering to get a wi-fi only tablet. The problems are that I'm not sure if it will tether with my phone (nokia e71; a lot of mixed reports about tethering with the phone) and wi-fi is not really available in many places in my area. So i'm preparing for the worst case: no internet once I'm out of home/office. Does tablet have any use in such situation? Does it become totally worthless if there is no Internet? If no, what do you use internet-less tablet for?
