MS Requiring More Expensive Vista if Running Mac

ktwdallas writes "Mathew Ingram from Canada's Globe and Mail writes that Microsoft will require at least the $299 Business version of Vista or higher if installing on a Mac with virtualization. Running the cheaper Basic or Premium versions would be a violation of their user agreement. According to the article, Microsoft's reasoning is 'because of security issues with virtualization technology'. Sounds suspiciously like a 'Mac penalty' cost that Microsoft is trying to justify."
