All these graphs are BS except the one about OS fragmentation. Devices and screen sizes are not "fragmentation" any more than people viewing their browsers on different screens or resizing windows represents fragmentation. That is just the reality of a viewport that potentially has many sizes. It is a FEATURE. Is it harder for developers?? Of course, but blaming it on fragmentation is a cop out. The OS thing is real and really worse than what is depicted because depending on the APIs you are using even OEM specific tweaks introduce additional variables.
