I use SheepShaver on my WinXP machine, mostly for Photoshop work or just to reminisce. But I also recall not being able to run MS Office 2001 on it either. Bah.... doesn't matter anyway, I have the Windows version of Office anyway. Running Office under emulation wouldn't make much sense, performance wise. You'd probably be better off getting the updated OSX version of Office (which should last you a good 4-6 years before becoming obsolete).
