My girls don't actually need the tablets for their classes but more for taking notes along with going to sites used in class. They have their laptops, but would like a tablet to carry around instead we do not want to pay for data, but use wifi in hotspots, home, etc. as for a price range, I would say I would like to stay at $350 max per tablet. I was also thinking a 10 would be good. Modes the Samsung Galaxy require a data plan? That is one they've talked about.
