Once you go Zune you won't ever go back... lol. I had owned two pods before and they were ok. A 2nd and 3rd gen nano. But they were too small for really any video. I tried to watch some on my 3rd gen but it was tiring. The audio quality of the pod doesn't even come close to the HD.
I like all kinds of music. I will listen to anything from Trey Songz to Toby Keith or the rock classics to todays AFI and Silverstein.
