Year of Linux on desktop
I think Windows users are so used to "this will never come" that one day it will catch them by surprise :)
And no, it probably won't be 2016, nor 2017. But give Microsoft enough time to sell subscription to Windows-as-a-service without option for permanent license, Steam to push game developers far enough, kernel hackers to improve on nouveau and amdgpu, and few other bits to fall into place. It will take a long time, there is little incentive since Linux already rules where it matters, in the datacentres, but we will get there when people start paying attention to their privacy on desktop eroded to nothing.
