I think the days of the Windows monopoly are already gone - in my (academic) circles at least, I see more OS X/Mac than Windows users.

The OS X dominance is probably less sustainable than the Windows monopoly was, as it depends on one (already abusive) company for both hardware and software. In addition, mobile devices are increasingly taking over, shaking up the entire industry.

To me at least, it seems to be turbulent times where there is absolutely room for changes to happen. Not saying it’s going up be the year of the Linux desktop though, that one is getting a bit old.
