"The program was panned by customers"
Entirely understandable - Vista is just a nasty OS. Oh sorry, I misunderstood... you meant the Family License pack for Vista. :D
Seriously though, if someone was to offer to let me get an additional pair of Windows 7 Pro licenses for - as an example - less than £150, then I might be tempted. Especially if said licenses were permitted to be run as VM's under VMware.
I'm seriously contemplating giving Mr Tesco £90 for a Windows 7 Pro (IE-less) edition at the moment - which for a dedicated Linux geek is staggering, but the release candidate has been impressing me in use.
