Newsflash: Most of us have reasons for why Apple sucks. Just because we don't feel the need to wax poetic or pontificate at length about it doesn't mean it isn't there, it just means we don't feel like it.
Or, rather, they don't feel like it. I, on the other hand, love waxing poetic on how I can't stand Apple. Yes, they make legitimate decisions about what they think the best computing experience is. My problem is that there is no room for me what-so-ever in their calculations; I am not allowed to make my own decisions about what hardware I should use, or what I'm allowed to install.
First, they remove my ability to build my own machine, which is akin to giving me a most excellent christmas present that requires assembly, but not letting me put it together. Sorry, but you just took 98% of the fun out of getting a new machine. A pre-built computer feels like I'm always using someone else's computer - not mine.
Second, I have to jump through hoops just to get any app I want, even if I am willing to take the chance that I might be screwing myself over. To Apple, an informed consumer who is willing to take the risks regarding hardware (traditional computing devices) or software (ipod touch, iphone, ipad; the walled garden approach) is not welcome in their universe. Or so unwelcome that they make them jump through a ridiculous amount of hoops just to do something that should be patently trivial.
Apple isn't trying to market to me, they're trying to market to people who expect someone else to make everything work for them. I'm quite content (maybe even happy) doing that work myself, I feel like using OSX is akin to being told to tie my shoes with my teeth. I'm sure there are people out there who can rip through that in seconds, but it feels alien and cumbersome to me. Maybe it's seen as "better" by some, but better is a truly subjective term; I decide what is better for me, not an Apple UI engineer (who I am sure spend a lot of time thinking about it, but that still doesn't mean I like it better!)
I don't expect this to change your mind - obviously you're content with Apple, and I honestly think that's great. But don't sound surprised when those of us who feel constantly patronized and pressured by the Apple Marketing department and their volunteer wing, Apple Evangelists come calling. I don't mean to offend you, but an Apple Fanatic is precisely as bad as a Jehovah's witness interrupting early morning sex on a lovely Saturday morning. To expect those of us who don't respect what Apple produces to love you for pushing it is just irrational.
(Not that I hate loud apple fanatics, any more than I hate the Jehovah's witness who came-a-calling, but I certainly reserve the right to hate what they do).
