don't confuse their mobile business for their desktop one. to a very good approximation nobody uses OS X. iirc its something like 2-3% of the market share.

the things that make apple the bulk of their money, and which they have done successfully are the mobile devices - ipods, iphones and ipads. outside of a few niche areas where they are a standard platform (design type stuff mainly) they are not the first choice.

sadly most people i know with macbooks never boot up OS X - the ones who do are mainly developers who use it because Apple force them to if they want to target the iOS or OS X platforms. the rest buy them too look pretty and have the apple branding because macbooks have some prestige about them - but they nuke them and put windows on them because for anything much beyond web browsing, e-mails and light office work and a few niche tools OS X is hard to use for getting your job done or the other most common uses for home machines beyond web browsing, like games, videos and music.

"excellent in calibration and color reproduction."

i'm yet to see a display on any apple device that can be calibrated properly or is good for working on in a normal lighting environment (i.e. an office, or outside in daylight) due to their insistence on shiny coatings. the fact that they include colour profiles in the os with names like "sRGB" is especially galling... and that apple fan boys insist they are amazing compared to an actually calibrated monitor can be a real headache for a developer.

this might be a lack of experience with the devices, but i have used several generations of imacs (since 2011) and the new 5k monitor (not the 5k imac though).

... however, they do look visually stunning in my subjective opinion, i can't take that away from them. the colour profile may not be technically correct or especially helpful for precision work, but the contrast and vibrancy of colour are very visually pleasing... provided your room has diffuse uniform lighting and few direct light sources that put glare and reflections on your screen.

please, please, please. 100x please. don't be afraid of speaking out.
i would paraphrase the advice i was given by a long standing member of the programming community responsible for leaps and bounds in the way we all work (without naming names, so consider it my own advice)...

"it doesn't really matter how much irrelevant people hate you if you can prove your worth through work and delivering tangible results... there is always another job, and you can always work for yourself if you are good enough"

feedback works both ways, and myself, I mainly give strong feedback upwards and not downwards, and without pulling punches. when going downwards it seems important to balance the feedback to give the best results, to frame it correctly for maximum effect. if my boss can't do their job and wants to do something objectively stupid, then they need to know it in no uncertain terms that they are shit at their job and that their decision is evidence of this. preferably in more aggresive language than that and with a stance of 'i tolerate zero bullshit'.

the great thing about being actually right is that every single part of the universe is on your side. it doesn't matter how rich and powerful they are. right is right and that is the end of it. the more stupid of this kind will gladly spend hundreds of thousands or even millions in trying to suppress your views, but they will naturally fail if you are backed up by every single thing that exists.... and get a strong lesson in how money doesn't buy everything.

you can't bribe reality.
