I guess I would agree that WIN 7 would be the go , if you want to spend the money.
However as your ancilliaries die I would think you will find it increasingly difficult to get XP drivers for new printers etc, as MS will at some stage drop XP.
My Vista has been quite stable especially since the SP1 so IMHO if you want to run something run Vista. I run one XP Sp2 and one Vista and I now prefer the Vista.
