I like this because I'm interested in creating more cross-platform projects. By that I mean, not only does this webapp work on recent versions of Internet Explorer, but a developer can easily get up and running on it using windows (as well as Linux or OS X). I don't want a situation of “you should really be using this OS to develop on this project, and not those other ones”. I don't want to go out and pay for windows just to do this. It's not my primary OS, and it isn't going to be. But I do want to be able to say, “you can easily develop and run my app on Windows”. Having something like this from Microsoft might be just the push I need to make that happen.
