I've been seriously considering cutting AT&T out, and just using skype over wifi. I hardly ever make or receive phone calls - everything is SMS or email. The thing that keeps me from it is the knowledge that, with a data plan, I don't have to worry about getting lost. With a data plan, I can be certain my contacts are backed up. With a data plan, I'll get that SMS when I get off the subway and plans have changed. And that I'll never be able to get the same data plan I'm grandfathered into.
