Windows can already be virtualized. The problem is accessibility and cost. We've seen that most users can't be bothered to upgrade machines. You have to give them an old-car, new-car model: copy all their precious data, then throw their entire box away and give them something new that happens to be running Windows virtually. A virtual PC must be as easy to buy as an iPod. It must be cheap (free of any nonsense about not being able to reuse old upgrade-only copies or otherwise paying again for Windows). A program that would let people trade in old PC hardware for fast new virtual boxes would be ideal: something that copies their entire Windows image onto it right at the store, preserving their files, much like you'd trade in your car and keep whatever stuff you had in the trunk. And, it must start looking "uncool" or almost unheard-of to use anything else as a Windows PC, similar to the effect the iPod has had on other music players. It has to feel "ridiculous" to the average person to keep using some old clunker PC, it can't just be something that tech people would think.
