I own a Core i7 Mac Mini, in the two years I've owned it, it's slowed down significantly since updating to Yosemite and subsequent upgrades. I can't imagine too many Mac users using Linux.
I don't have a problem with all Macs just the ones that are ridiculously overpriced and underpowered. I don't even have a problem with all Apple users, just the ones who constantly keep praising Apple no matter what they do or what crap they bring out.
If you go to Microsoft forums or Android forums people will berate these companies if they do something wrong, with a lot of Apple lovers they just gloss it over.
In my opinion it's why Apple is so expensive and brings out such mediocre products lately, they don't have to try to hard to please the followers.
Just imagine what Apple could do if people were up in arms over some some of the latest missteps.
I won't even bring up how many times a day Safari crashes on my iPad Air.
Oh, have you seen what happens on here when someone complains about their Mac or iPad because it's playing up, the fanboys berate them and tell them they're just a hater.
Oh there are a few of us here who are just as happy to call Apple out as we are to sing it's praises.
I would agree with you, that Apple make some really questionable decisions sometimes. The obsession with thinness at the expense of things that are kind of useful (you know, like batteries and USB ports among other things) frustrates me, as it does many Apple users. But I disagree with your assumption that Apple is getting complacent because its fans are blindly satisfied with mediocrity. You're focusing on a fairly small but vocal group on these forums who will, as you say, praise Apple no matter what. If you know anything about the Apple corporate culture (the one Steve Jobs instilled), it's absolutely obsessive about design. I believe they really are seriously motivated to produce the best products they can. I just think the priorities are skewed. Whereas most users would gladly suffer an extra millimetre thickness on their iPhone for better battery life, Apple's designers are too excited about how thin and light they were able to make it to give us that.
Something's gone wrong with Apple's software too. I've been using Apple products for over 20 years, and I don't remember things ever being so prone to annoying little bugs at every turn. I remember problemssometimes serious problems, like the old Mac OS crashing (and crashing hard!) and battling with conflicting extensions, etc. But I don't remember the sheer volume of buggy annoyances that seem to hound iOS, OS X and iCloud. Things are no doubt a lot more complex now, with iCloud integration, the online stores, etc But Apple used to be proud to advertise that their products 'just worked'. That slogan would seem a bit embarrassing these days.
