HSDPA on a Fujitsu U810: 3697 kb/s Upload (video demo)
Fujitsu introduced two computers with AT&T's HSDPA built-in today and I got a chance to play with them. I pointed the U810 to speedtest.net and was blown away by its upload speed. The speed test starts off slow on the download portion, but the upload speed shoots to 3697 kb/s! I've been struggling to get 10% of that speed using my Sprint EVDO cards.
