Had a play with the Mozart over the weekend. And I must say it really surprised me. I was I impressed considering the flack the older HTC models have copped.
It was reasonably quick (although that could change once loaded up). I liked the way the menus were layer out, and they have made it very social networking friendly (facebook runs live on it's desktop iirc)
A little skeptical about the whole requiring windows 7 to link it to a PC, but hey, that's coming from an iPhone user who can't do shit unless DieTunes is installed
