I have to be honest here, while I would hope for a complete down fall the reality is I see Microsoft dropping from 90% of the desktop to more like 60-70% as Linux and Mac will make up the difference.
Microsoft will suffer losses but the truth is (and that's barring some major miracle) they will still be the dominate player in the desktop arena. Just not as big or strong as they used to be. And this is good for US the consumer.
