Touch is the King of convenient music playing (if you don't mind being locked into iTunes and restricted formats). Movies are pretty nice also - smaller screen, but more colors and great sound. Touch is smaller with nice interface. N8xx is better for sharing music/movies with built-in speaker and stand. It's also best for internet radio.

ITs have the browsing experience down. As long as there is support, they can pretty much keep up w/ the web. But the Touch just had an update that allows for more video sites than just Youtube, so that is another point for it. If they open it up, like it's said for Feb. '08, then it may surpass the Nokia in some, or maybe all, web browsing options.
