As I read this, you go to the store and buy a copy of Vista, which you install on a PC you had in your office. A year later, another PC becomes available that's a bit more up to date, so you decide to transfer your Vista license to that machine.
You're now finished with that Vista license. Done. Game over, man. Whether you shelled out $199 for Home Basic or broke the bank with the $399 Ultimate makes no difference. You've reassigned the license twice, and that's all that Microsoft allows.
