> So developers will turn to an OS
Not really, I would say it's about 40/60 Linux / OSX (or whatever Apple's system is called nowadays). They produce the software that makes things such as posting your very comment possible.
While having nothing much against Microsoft's operating system per se, in terms of sheer usability it strikes me as a throwback to the 90s and I have to wonder by what feat of marketing people are still using it.
Bit like Ubuntu, mind.
