There are a half-dozen CTA (Chicago) Bus Tracker apps for iPhone/iPod Touch. A couple of them apparently use GPS to know what stop you're standing at. If (like me) you don't have a smartphone, you can get the next three buses for any given stop via text message. Darn handy in the winter.
I'm pretty sure they have them in San Francisco and a few other cities as well.
