This is an important point. It seems one can never quite escape fragmentation due solely to time moving on, let alone the complexities introduced when targeting multiple pieces of hardware. Reading this article I kept thinking "OpenGL and DirectX". One could argue each has its own monoculture with respect to Windows (or X-Box) and non-Windows OSes, but each monoculture is still fragmented. Windows devs still target DirectX9--initially released over 10 years ago, and the latest DirectX11.1 update will only work with Windows 8. OpenGL is just as bad with the 3.0 flop, issues with the move away from fixed function pipeline concepts, its ES version, and WebGL...
