Deciding on buying Vista for Macbook pro

[SPECOPx]

Want to buy vista and it would be the only computer I would ever need to install Vista on period. So my question is if I buy the OEM version and install it and want to restore my whole computer to factory settings at a later date would I be able to reinstall Windows Vista OEM on the same computer again?

Yeah, it's just tied to that machine.
