I'm on the $30 plan and hit the cap every single month because I'm using it as my home internet. I absolutely refuse to do business with AT&T -- the only cable provider to my apartment complex. I can't imagine I'm the only person in this situation, and wish I had a better option, such as a fixed rate (i.e. X bits/second transfer cap) to the local cell tower at this one location that I actually use data regularly rather than a fixed number of GB per month over wherever they have coverage.
