The previous plans were not unlimited--they were capped at 5GB, IIRC. That is reasonable. I think even your local internet cable connection has a max. 250GB transfer limit. Thing is, these are rarely enforced and present for worst case scenerios. AT&T said that 98% of its customers will save money by switching to these plans. I am more concerned about the future consequences. High bandwidth content over mobile is in its infancy right so usage is no where what it will be a few years from now. That is when AT&T will be making a killing because by then, use would go up and people would be used to this notion of paying by the GB. I know this because I saw this in action in India. Initially, in the 90s, the ISPs had few gb limits. It didn't matter because all you used the net for was email. Then came broadband, napster, and torrents and guess what? The concept of buying by the GB carried over.
