Regardless of the license, I definitely like the direction Microsoft seems to be going in. First they make Microsoft office online free to the public, there's talk about windows mobile one day being free, and now this. All within a rather short amount of time. I don't see myself switching from GNU/Linux any time soon however, but I hope Microsoft will soon realize the potential of Open Source. One company I really appreciate is Adobe, they put a surprising amount of effort into Open Source, and also released Photoshop v1.0.1 source. On a side note; I wonder when Windows' will post their first project on Github.
