As long as you've got the latest versions of all your software (and it all supports Vista) then you're golden.
Few features were lacking in CS2, mainly working with raw photos and exporting PDFs, CS3 fixed that.
I do find that I can have less progs/windows open at once than with XP - it just refuses to let me open any more rather than bog down and crash.
Interface is pretty for a week or so.
I use home premium FWIW.
