They could turn it into even more than delivering software on Windows. I'd pay to have a virtualization layer that transports settings/environments across my computers. For example, I like to set up custom keyboard shortcuts in my text editor, but every time I set up a new computer I have to reconfigure all of those settings. That shouldn't be necessary.

BTW I feel like the TC article didn't communicate the key point very well. They didn't mention virtualization until eight sentences in.
