Now lets compare that to apple who releases a new OS every 1-1.5 on average with a cost of $129. So when you comare that to 3-4 Apple seems to pop off the the time of one over MS OS windows looks a hell of a lot cheaper.
Yes, the fact that Microsoft only releases a decent OS every 10 years makes it a real bargain.
As a niche (5%) OS, Apple's stuff should be more expensive. Do you think it takes less effort to create an OS just because you hold a very small piece of the market? Of course it doesn't.
Microsoft's 95% stranglehold on the OS market, on the other hand, should net me a copy of Windows 7 Ultimate for around $49 retail - if you want to talk about "reasonable" margins that is (but of course you don't).
Where's the outrage?
