An anonymous reader writes "Mac users wanting to run Vista on their Macintosh, alongside Mac OS X programs, will have to buy an expensive version of Vista if they want to legally install it on their systems. The end-user license agreement for the cheaper versions of Vista (Home Basic and Home Premium) explicitly forbids the use of those versions on virtual machines (i.e., Macs pretending to be PCs)." Update: 02/08 17:50 GMT by KD : A number of readers have pointed out that the Vista EULA does not forbid installing it via Apple's Bootcamp; that is, the "tax" only applies to running Vista under virtualization.
