Q: do most people really have the data plans on their mobile devices to be able to listen to music all day? I'm in Canada and we certainly do not.
As an American who living in Canada though, you guys are screwed beyond belief. My girlfriend pays for internet BT THE SERVICE. I think the android plan allowed twitter/AIM/Facebook, and BlackBerry was email/bbm or something. That's the kind of thing Americans only imagine as a dystopian future: http://www.microsiervos.com/images/TieredInternet.jpg
