At one point that may have been the case. Nowadays things are a little different. The Linux kernel is up to 17 million lines of code, receives an average of 8.5 changes per hour, 10,000 lines of new code added per day, over 10,000 changes made per stable kernel release. It's used on billions of devices world-wide from the Xbox gaming console, to desktop and mobile PCs, to mobile handheld devices, to car engine control systems, to home appliances, and even a nuclear submarine.

The Linux of 2013 is not the Linux of a few years ago.

There is no other operating system that comes close to this level of hardware support, this level of stability, and this level of adaptability by the developer community at large.
