Gil Asakawa has a brief paean to the wrieless revolution in last Friday's Denver Post. Personally, I love where this is going. Right now, the main restriction is the fact that there's no service-sharing. Starbuck's has T-Mobile, but the airport is on AT&T, and I don't care all that much for Starbuck's coffee to begin with. I like Panera, and their access is free, but because of that I can't get to my old SMTP server to send mail out.
Still, these are details, soon to be worked out. There's no reason this can't be dealt with the same way as phone service. Now, if they can just do something about battery life so I don't have to be tethered to a wall the whole time...
