I am not saying “This is the Year of the Linux Desktop”. That said, things languished below 2% for decades and now it has doubled in just over a year. With the state of Linux Gaming, I could see that happening again.
Also, if ChromeOS continues to converge, you could consider it a Linux distro at some point and it also has about 4% share.
Linux could exceed 10% share this year and be a clear second after Windows.
That leaves me wondering, what percentage do we have to hit before it really is “The Year of the Linux Desktop”. I have never had to wonder that before ( I mean, it obviously was not 3% ). Having to ask is a milestone in itself.
