I bought a Mac because I hated Windows. It's been a struggle, though because Mac hardware is so damn limited in choices, but once in awhile they would release something decent and the notebooks were often quite good (as long as you didn't expect a gaming machine). But make no mistake, it is the Operating System that makes Macs special. That is why I've put up with a lot of crap from Apple in the past, but let's face it, that only gets you so far, especially when Windows 10 isn't anywhere near as awful as something like Vista was and it even has many OS features now that Macs and Linux had cornered (e.g. Spaces/Mission Control functionality) and have now gone ahead with Cortana while Siri is nowhere to be found in El Capitan. Microsoft has pulled ahead of Apple in many areas and stability and lack of malware is about all that's left. Other features have gotten worse over the years (i.e. Perian + Quick look used to equal AWESOME but when Apple changed Quicktime to AVFoundation in "Quicktime X" it's like its now OS X's cheap cousin or something. "You should convert all those 'old' formats". Yeah, why should I have to? You lose quality when you convert lossy formats into other lossy formats.
Apple is losing site of the forest for a few damn trees (called quick profits rather than quick look) on almost every front. Tim Cook is a business man interested in profits (buy-backs, dividends and features like a stylus that Steve Jobs hated and would never support.) It's sad, but unless things change, I'm afraid Apple is headed in the wrong direction at best and has its days numbered as a desktop OS (I'm sure phones will continue unabated for quite some time). The sad thing is I don't think Tim Cook really cares one way or another. I believe people under him could fix the situation, but that would mean getting past Jony Ive's massive EGO and getting back to the rationality of someone like Scott Forestall who got iScrewed by Apple over something beyond his control (i.e. you can't make Maps perfect overnight).
