98% of computer-using population will use whatever comes with the machine; Linux is viable but the hardware vendors are not pushing it, also because of Microsoft lobbying. On the other hand Android could be easily built on top of QNX and get the same market share.
It does though. If Linux & Apple didn't exist, Microsoft would have a much shitty product. Kind of like apple's browser, since it doesn't matter that they keep it up to date since they have lock in.
Sounds convincing but a lie. Unfortunately, those pesky facts just keep getting in your way. Microsoft has always been the laggard in browser standards.
Also, Linux works fine for plenty of people, sure miniscule in proportion, but it hasn't failed.
