I can get Vista Business for pretty cheap through my school's MSDN website, and have read that if you purchase a copy of Vista now till the Windows 7 release, you can get a corresponding Windows 7 Upgrade (in my case Windows 7 Pro) for free. Does anybody know if this applies to a school MSDN subscription, or does this only apply to retail stores/copies of Windows Vista? My account is probably going to expire soon, so if I can get Windows 7 Pro for cheap, I'm going to get it while I still can.
