Well, you know. This would kill the PC market - thats the reason Apple did it.
Why I would love a mac, but having two computers in the same room is a no go.
But say, having a mac mini plugged in and being able to have windows on it, means I can migrate from my PC to a Mac mini AND get rid of (sell on eBay) my current PC - which is getting old (2years old).
So effectively this will move droves of people over to Macs, because retailers can setup Macs to boot windows too. This will mean theres now no reason NOT to own a mac (until Vista comes out anyway).
You don't think that project with that big prize was secretly funded by apple?
