Here I am, sitting in the passenger waiting area at the Amtrak station in San Diego. It's a typical train station. Noisy, wooden benches, pretty low tech. I have 2 hours before the train arrives (if it's on time), so I open the old 12" PowerBook and start to read some emails, when what to my wondering eyes doth appear - a little note from Airport that it has found a wireless signal named TrainDepot. Would I like to join? You bet your sweet bippy I would. It's FREE. So I kick back on the bench and not only read email, but compose and send email. Awesome. It is only then, I notice a homeless guy sleeping on the bench across the aisle from me. If an enterprizing photographer had been handy, he/she would have been to snap a pulitzer prize winning shot.
