Actually, much more real world is to take a large site and always take the same site/total time that it takes to complete the download.
I usually use howardforums.com....11-12sec with wifi, 18-20 3G...these haven't changed post 2.1 compared to pre.
I have horrible 3G speeds at the office. 185kbps, basically the same speed as EDGE. I'm going to test at various places in the few days, but if I don't see an improvement, I'm returning the phone. No sense in paying $15 more a month when you're not seeing the speed improvement.
