Only 2 people on my Uverse section (not sure the technical term). Designated with a 32/5 connection, but they limit web to 24/3.
Flash, pdf viewing, and possibly video chat are just about the only thing that the average user would need something over maybe 3 or 4 mb/s. I agree with jdubb, average users won't really need anything over 3 or 4mb/s on the average day.
jdubb, you tried www.onlive.com yet? I was fairly impressed by it, but even with amazing internet speeds, there is still a bit of a lag.
