Poor Linux. It struggled so hard to dominate the world. It was the little open source engine that could, but it didn’t. It never even came close to Microsoft Windows on the desktop, with less than 2% share of desktops. The bright spot for Linux is that 60%+ of servers on the Internet run Linux.
The mobile platform space is extremely fluid, and I do not think the open source community can muster the forces necessary to compete. Open source never seems to be the innovator. Instead, it seems to disrupt pricing power for established technologies.
Game over for worldwide dominance. But server dominance is nothing to sneeze at.
