Scott Hanselman has a very interesting quote from “super-secret-have-to-kill-you-sources”.
Now for the good word. Rumor is that Microsoft already have Vista
running on iMacs on campus. Likewise it’s rumored Intel has a Vista
build running on Mac hardware. So it not only feasible for some users,
there is a reason other than just the pure challenge for a good many.

I’m not surprised that both MS and Intel would be interested in seeing this work. I’m pretty psyched about it as well. I think that the iLife apps are really nice, and the Apple hardware is beautiful. I’m not sure if I’m willing to give up my Tablet for a MacBook, but maybe if they come out with a 12″er. I still think it would be way more useful to have VMWare on OSX, and maybe a version that support the virtualization that the CoreDuo chip can do.

What is the status now of Vista on iMac Intel?
I haven’t seen anything on Vista on iMac in quite a while. I suspect that Boot Camp (http://www.apple.com/macosx/bootcamp/) will eventually work for Vista also (if it doesn’t already.)
