I need more storage space on my iPod and I'm thinking of upgrading to an iPod Touch or even an iPhone, although I don't like the idea of having to go with AT&T. The cell I use now works fine, though it's pretty basic. Does it make sense to keep my current cell and T-Mobile account and buy an iPod Touch? I would like to have internet access, maps and simple PDA functions, games, etc. without having the extra burden of a $60.00/mo. contract. How does having a cell + iPod Touch work for you? Do you wish you'd bought an iPhone instead?
