The rise of the Linux hyper-distro
Linux as a one-size-fits-all operating system may be fading into the background as new specialized distros assert themselves in consumer space.
This is not to say that Linux is going away. Hardly. If anything, the sheer pervasiveness of Linux is what's fueling the trend to which I refer: the rise of more specialized distributions with one or a few major objectives that stand apart from the idea of an all-in-one operating system.
This outcome was inevitable, really. The modularity of Linux as a kernel and operating system has fostered a steady stream of appliances devices and software platforms for some time.
