A lot of stuff seems to work better now. I've bugged a few things... but I think I can almost start using this without getting seriously frustrated and annoyed.
I did a parallel install to my XP Pro; since Vista always renames drives letters (making iself the C partition,) my "Previous version of Windows" no longer boots. I just did a "bcdedit /set {ntldr} device partition=e:\" to make my old OS boot again.
