I ran some errands before work this morning and stopped by Circuit City to see the Zune. It was all strapped up with hard plastic covering any sort of port. Most disappointing was not being able to really "hold" the unit. They had 2 side by side, the one on the right was a brown non-functioning unit. On the left was a white unit you could try out. They had the white one hooked up to a speaker set (I think it must have been this Altec Lansing
set up for the Zune, but they were using a line-in instead of the built-in Zune cradle.
Just a few steps away were the rest of the portable music players, including the ipods. It was nice to be able to hold them in the hand, though neither of the ipods had any music on them.
I went by a Staples a couple of doors down and they had the exact same setup.
Overall, the Zune was nice. I don't have any player at this point, so I'm not married to a certain UI. I did think the horizontal perspective for video was nice. Still, just walking in, I might lean toward the ipod simply because I could pick it up, hold it, and get a real feel for what using the device might be like. At this point, either is safe from my wallet.
