Microsoft is trying really hard to destroy itself. I have always developed software for Windows and this really bothers me, because if they go down, they probably take me with them.
Windows 8 (its walled Metro apps) was a big attack on software developers and I still feel betrayed by Microsoft. If I was deciding what OS to develop for now, I will not be Windows. No amount of Blue is going to change that unless Microsoft reevaluates its goals.
