I'm a WiFi pirate. The wireless card cost $20-something, and I don't pay monthly fees, so it totally kicks.
Currently, I siphon off of my home's DSL, but my mom shuts it off most of the time so I borrow a little bandwidth from my neighbor's cable. I'd stick to the cable all the time if I got a better connection to it, but I only get a 50% signal strength most of the time, so it's usually more reliable to go with the slower stuff. When I move up to Logan for college I'll get free WiFi, I'm assuming a T1 line, but it'll be shared with others, so it probably won't be amazing.
Currently, 728/256 I think. A few days ago I was getting some killer speeds, though, at the peak I was getting about 1Mbit upload speeds, I don't know what the download speeds were, but they were up there, too.
