iOS gaming is on the rise to the detriment of Windows gaming. For years Microsoft had leveraged its DirectX API to keep Windows the king of gaming. Now Apple is becoming ina position to do similarly for the Mac.
I don't really like Windows, but I don't think I want Apple to be king of gaming when the are continuously finding ways to break old apps. They are breaking 32-bit apps and will likely be doing the same for OpenGL in a few years. These aren't the first times either. Before this it was the PPC to Intel switch, before that it was classic to OS X. After Apple drops OpenGL, the next move will be breaking all x86 apps in a move to ARM :/
I just want all my apps to work forever and don't want to have to worry about how long it will be until Apple breaks them.
