I wouldn't dismiss the smart phone so easily. Yeah, a lot of people use them to play games and do other trivial tasks, but the popularity of the iphone pushed telecom companies to radically upgrade their infrastructure, and while we are not there yet, hopefully the end result is fast, ubiquitous, and cheap connections to the internet around the globe. We are already seeing some of the possibilities, and I can't even begin to imagine what the future will look like (if I could, I would be feverishly working to make it happen), but wireless internet is certainly going to be a key component, and we have the iphone (or more precisely, the popularity of the iphone) to thank for getting it started.
