Maybe being anal is M$oft's forte but why be so restrictive?
As seen on Digg.comMicrosoft has published the planned licensing terms for Windows Vista. As reported on the HardMac forums, the version-specific addendums contain clauses that specifically address usage of Vista in a virtualized environment. For both Home Basic and Home Premium editions, they state that "You may not use the software installed on the licensed device within a virtual (or otherwise emulated) hardware system." For other editions, such use is permitted but restricted:
You may use the software installed on the licensed device within a virtual (or otherwise emulated) hardware system on the licensed device. If you do so, you may not play or access content or use applications protected by any Microsoft digital, information or enterprise rights management technology or other Microsoft rights management services or use BitLocker. We advise against playing or accessing content or using applications protected by other digital, information or enterprise rights management technology or other rights management services or using full volume disk drive encryption.I encourage anyone considering Vista to go read the whole EULA. These are not the only obnoxious clauses, just the ones that are especially relevant to Mac users.
