I've been using Linux as my primary desktop OS since 1993. I worked as a technical editor focusing on Linux and Open Source for a number of years at iX Magazine and Linux-Magazin in Germany. Also, I worked in IT consulting for 25 years, specializing on Linux, Open Source, and some other Unix. For decades I have been hearing this "will XXXX be the year of the Linux desktop?".
Do I care? Frankly, no. Open Source has always been about choice. May others use (and frown upon) their Windows or Mac boxes. My choice was Linux, and will remain so, mainly because I hardly have a use case for something else, and Linux does nearly everything that I need it to. If occasionally not, KVM and Virtualbox are my friends.
