Now we're talking. I don't expect it'll ever be as smooth to develop with Rails under Windows as it is under actual Linux, but if it were as good as OS X, I'd say this was a success. But, then again, maybe this subsystem really will make it feel native. As a matter of fact, this was the only use case I could come up with to test the implementation of this announcement. I'd like to think that I speak for enough people to make it worthwhile to suggest that you should do a writeup on your experiences with this. I'm strongly reconsidering letting my main machine re-upgrade to 10 to try it, but it works really nicely for gaming right now, without any other cruft. ;-)
