Well, I had the opportunity to play with a zune today. It was the white one, and I must say, the casing is impressive. It's a lovely semi-opaque (for half of the depth, and opaque the rest of the way) matte finish back with a solid white front. The screen is simply amazing for 320x240. Sharp, vivid colours. The unit itself is not evenly weighted, one end being heavier than the other. Being used to the blazing menu response time of my nano, the zune felt slow, sort of like the ipod mini, everything takes a millisecond of time, not nearly instantaneous. Interface was nice and intuitive after I got past the fact that the fake scroll wheel is actually a 4 way d-pad.
No sq report, as I didn't have my e2c's with me at the time (it was a microsoft info session (co-op/intern job related) at my university).
