@papboomboom there is also the Note that is coming out and that has a 5.3" screen. Many phones, however, offer email and other common features of a computer that are most often used. I think an android device would be nice but you may get just as much out of a cheaper phone, perhaps a Blackberry device, than an android phone. That assuming you wont use the features of android very much.
If you want to explore a smart phone maybe the Note is right for you? simply because of its very large screen.
