Damm you did mention something about a showoff at the meet. This looks awesome ! You should have got it to the meet. It would have gelled well with all the audio stuff that was there !
OK, so I managed to have a look at it yesterday, and the first thing you'd notice is the gorgeous screen, I mean it's smaller than the ipod but very very crisp, and videos looked really awesome.
The interface too was a big surprise, coming from MS , never expected it to be this fast and pretty. Overall it's a nice alternative to the ipod.
