XP Pro x64 would be a choice but MS for some strange reason decided not to let Office 2010 install on it, not even the 32-bit version!
Yes, it will if you run 32bit installer in XP compatibility mode. I just did that few days ago.
For me however, as a notebook user, XP 64 has another very serious issue – no hibernation with 4GB ram.
