Battery life is probably as important as size for merging the tablet and phone markets. My tablet is effectively an extended battery for my phone. I could probably use my phone for everything I do on my tablet, but if I did, I'd be charging my phone 2-3 times a day. As soon as the size gets more usable and battery life improves sufficiently, tablets will probably turn into a fringe device.
