Unrelated question: How do you like your iTouch? Do you use it as a PDA replacement? How is the WiFi internet speed?

I briefly played with one at the Apple store yesterday. My impressions:

(1) I felt the keyboard for alphabet text entry was a bit cumbersome, though nowhere near as bad as typing on my razor phone.
(2) The sound quality (with apple headphones) was much better than I expected, but then again I was raised in the era where walkman cassette players were cutting edge.
(3) Magnifying the web was not as easy as it looks on the commercials.
(4) Lack of separate external volume control was really annoying. Also would be nice to have a "back" button.

Despite these shortcomings, I still thought it was amazing light years ahead of the competition.
