Looks OK but Microsoft are taking far too much notice of their competitors. WMP is a **** poor rip-off of i-Tunes for starters, and those screenshots look a lot like a Mac.
I wouldnt touch Vista for a while yet anyway. Remember how long XP took to be reliably stable?
I work at a school as a techie and they still use 2000 cause its more stable on there network. I also know someone who beta tested both the 32-bit and the 64-bit versions of vista and he said wait a year till its more stable.
