Yeah, there's a lot of reasons why the touch controls Apple added to the 3G were removed for the Click Wheel in the 4G. Believe me, I've owned both. Of course, if they had announced a remote for the iPod touch, that would have helped greatly.

Note: it's the same reason why I don't use the Nokia as a primary media device -- usability demands that *some* actions are buttons for speed and accessibility in tasks. When I go out with my iPod, I'm holding it in my hand or in my pocket, thumb on the wheel, unconsciously adjusting volume levels, skipping back and forth, pausing to hear an announcement on the train, etc. all without looking at it. The N800 design just isn't as specialized for media, from the lack of a hardware media controls that work regardless of foreground app to smaller bumps like the unfortunate distinction between system volume and media player volumes.
