Windows is still by far the primary platform users (maybe not devs) use, and yes, for any serious project, it is most definitely a requirement. I didn't get the sense from the website that it wasn't going to come to Windows, just that they haven't had the chance to get it working yet. I don't find the devs attitude lazy unless they actually come out and say screw it we aren't going to both to support Windows.

And this attitude being displayed toward Microsoft is just lazy (and very likely the province of the young), because while they did give us a crappy browser and Webforms for way too long, and they are fun to poke fun at, they've done more than most companies to push both the computer revolution and the Internet as a whole forward to what it is today. So give them a little credit, pull your head outta the sand and actually take a look at what they do once in a while also. You might be surprised what you find.
