Ubuntu + Wine = Windows 7

I was reading Joel's latest post, about the architecture astronauts that are running MS, and it occurred to me that they're going in exactly the wrong direction. After all, Wine is great. I can run most of my apps on it with minimal fuss. As wine doors takes off, I can see that I'll be able to run them with different settings. Since Linux is already a much more stable environment that the crap Microsoft keeps pushing out, how long is it going to be before people start writing against the wine api and let people run their software wherever they want?
