One reason not to get a “home” version of Vista
Turns out that despite the fact that at home I’ve got an x64 quad-core PC with 6GB of RAM I can’t install the Windows 7 beta via Microsoft Virtual PC 2007 because I’ve got Windows Vista Home Premium and Virtual PC won’t run on anything less than Vista Business. :-(
However, I do have Vista Business at the office and I was able to successfully get Windows 7 Beta running via this method.
