Microsoft like Linux in PC desktop will never convince the masses there platform is worth investing in over established players. In smartphones Apple and Andriod have a market that has reached saturation in most first world country's tied up. In desktop Microsoft has a similar thing. So does Valve with steam. Windows mobiles market share has not gone anywhere in the last few years. Most of the surveys for people leaving Andriod suggest they will go IOS most leaving IOS go Andriod. There's so many things that need to change for Microsoft Mobile or OSX and Linux to see big market share gains. Apple is happy to be 8% bringing in the money. If Apple with 8-10% market share can not get games launched on its platform what hope does Linux have with worse driver support and a at best 2% market share. Best way to play Linux games is still to use a 980ti and throw Lots of performance at the problem. The next big thing in tech will be VR without Apple saying it will do VR I do not expect OSX to get VR support.
