As much as I want to joke that it is the year of the Linux desktop, I think it is mostly because the younger you are the less likely you are to have a pc (so Windows, Mac, Linux and BSD for the dozens of you).

As far as I can see most of the time people use their phone for everything and only touch a pc for work or if they have a hobby that requires the use of a pc (gaming, digital art, music, programming, etc…).
