I've only tried the Ultimate Edition. I'm getting it directly off my MSDN developer account. I actually re-installed lastnight because the system started to completely lockup on every startup. Explorer was hanging all over the place. It's weird, all my hardware is pretty much brand new, and XP would run for weeks and weeks without a reboot.

I think this time, I won't be installing vs.net 2003 directly on vista. I need to setup a stupid VM machine to load XP and all my developer tools.
