Besides the high cost of using a cell phone in Canada, could another reason be ease-of-use? Not necessarily the technology itself, but the process itself (credit checks, long contracts, etc.). Though I've never bought a cell phone outside of Canada, I have heard/read many sources confirming the simple process of getting a phone in Asia & Europe. Just buy a phone, get a SIM w/ a phone #, and you're good to go. Not that simple here...
Also, we are often way behind the "rest of the world" when it comes to new models & new technology. By the time it reaches N.America, it's an old, outdated model in Europe!
So yes, I agree that cost is a major factor, but it's not the only one.
