I'd be willing to bet everyone is using wifi at home and when available outside the house. I've never come close to using 2GB but use a lot of wifi. My college student son streams music (even while using wifi at his home) and usually bumps up against his 2GB limit every month. He would definitely be over if he didn't monitor his usage. If anyone is going to be streaming movies on netflix or music without wifi, 2GB will probably not be enough. With wifi, it would probably be overkill.
