As a full time linux user, it pains me to say it but there will never be a "Year of the Linux desktop". Not now, not in 100 years. Linux is the weapon of choice for a very small audience and the proprietary giants are simply not interested in a niche market. Some people can get away with using a raspberry pi as a main computer(myself included, given that I only use a browser and vim for work). But again - that's just me. Many of my co-workers rely on heavy IDEs so that rules it out for them.
