I have an n800 it works fast enough.

I was thinking about buying the iTouch, but like you said the lack of flash was a deal breaker. Also a another deal breaker is I really hate hate....did I say hate iTunes. I really dislike the way it manages music files. I want to store my music as .mp3's iTunes converts everything before storing it on an I(device) to some other format. That means I have keep my .mp3 on the computer or double store the songs on the device both as mp3's and whatever format Apple uses. Plus I find having the library and the idevice library a pain up to date.

I just really dislike iTunes.

Yet, another reason I went with the N800 was it was running linux, which I knew meant open-sourse and many free programs could be installed.
