I have both a Ipod and Zune....both are super sweet. Let me tell you something about the video part though....having 100% instant access to full length porns is the shit. Not to mention full length regular movies.
My Free Tunes is a good program for stripping the DRM protection from music downloaded form itunes, so that is a moot point now when considering the ipod.
I think the controls on both, but I think the Zune fits better in my mitts.
just my .02
