2GB of data a month is still seriously lacking. If the numbers are right, then for your average commuter who might view a television show while traveling to/from work on the bus or train would go through that 2GB limit within two weeks if not sooner. On the one hand, the phone companies know they never build in the infrastructure to handle so much data, but on the other hand the streaming media companies are looking at loss of business because of the limitations being placed.
For me, it doesn't matter as I'm one of those historical throwbacks who use a cellphone as just a phone. No streaming media, no text messaging, no web browsing, just call someone when I feel like it. Radical idea, I know, but the cellphone companies lose enough on people like me that they have to make it up in other areas.
