I’m cheating a bit. 2015 isn’t quite done yet, but the web stats are piling up.
See StatCounterGNU/Linux is apparently right back where it started despite a terrible slowdown in shipments of That Other OS on Wintel boxes and huge growth in the first quarter. I don’t know what’s with that but “Unknown” took off from there… Maybe it’s Google not including “Linux” in their Chrome OS User-Agent strings but can’t StatCounter still identify them as ChromeOS? Why “Unknown”?
Still FLOSS and */Linux grew amazingly thanks to Android/Linux and “Unknown”. I believe “Unknown” is */Linux because Apple and M$ won’t allow their OS to be “Unknown”. That leaves GNU/Linux likely although other platforms like MIPS and other OS like the BSDs are out there. Android/Linux is just off scale. It’s share of tablets and smart thingies page-views is ~60%, 27% against all operating systems, even more than “7”. The world is leaving Wintel behind just as fast as it can. Who needs the burden of CPUs costing a multiple of the cost of production and an OS that needs to be coddled and costs many times what */Linux cost? Yes, imagine paying double or triple the cost of your car and leaving it idling in the driveway most days… That’s the kind of waste Wintel has foisted on the world all these years. We’re done.
