All that I know is that since snow leopard the evolution of Mac OSX have been a disaster. The apple computer line has stagnated terribly. I never update IOS because each new release will probably screw up wifi and/or take something else away that works perfectly well and force me to change. Mac OS X plays less and less well with others, particularly open source. If this is all due to innovators like forestall, then I'm glad hes gone. Who knows who is responsible, but like Lincoln just keep getting rid of generals until you can find one who will win.
