Windows 7, aside maybe from some UI elements, is nothing like Vista, so don't be put down if and when people tell you it's like "Vista 2.0". Windows 7 is more like "XP 2.0", with Vista as the horrible beta :P.
Well, if he goes to Professional or Ultimate, he can run XP mode and have an XP virtual machine set up. Hell, he can use his own XP copy to make a virtual machine if he wants, and he can be on Home Premium. If you're building your own rig, I would really recommend Professional at the least.
