I dunno. I agree with you that "only works in Windows" is not a downside for MS, but.... I'd argue that the best way for them to make Windows a good programming platform would be to make it better and easier to program in the other languages already there -- C++, Java, PHP, Rails all work on Windows, just... not as easily as on *nix. Although I guess a new, good language wouldn't hurt.
