The year of Linux on the desktop was around 2010. The trouble is, I'm still waiting for the year of Linux on the laptop.
My NAS runs CentOS and I have Arch/Ubuntu on my home pc's, but I still dual boot Windows on one because gaming.
The 'I wonder who else will switch to Debian 8 like me' just struck me as comical.
I would be extremely surprised if MS lost any meaningful amount of marketshare from Win10, especially to linux distros.
Do Chromebooks count?
