I don't hate Apple, I just see their products as being overhyped and overpriced. Not to mention the "90% of tech is a direct result of Apple?" But wait... Apple for the most part has been smaller, and used other's technologies and just marketed them better. Now, if that were "90% of the tech you see in people's hands is an indirect result of Apple's marketing campaigns starting with the iPod." I would agree wholeheartedly. They just took an MP3 player, and marketed it for an aproximate number of songs it would carry rather than the amount of storage capacity.
While Blackberry had a smartphone out before the iPhone, and touchscreen phones had been out for a while, Apple gave it a sleeker design and a platform-central market.
Tablets have been out for years but Apple made one, put "i" before it, threw a marketing spin on it, and now most people are calling even non-Apple tablets iPads.
As far as using Apple products, I grew up with Macs, but I've always prefered windows as I can do more with it, and I personally do did dislike the single button mouse growing up. I used nothing at school (we started comptuer classes in 3rd grade.) but Macs until I got to programming classes in Highschool. Always built windows at home though.
Software-wise, part of it is that Apple refuses to release evolving software and they want a single, finished, no customer feedback solution, or if there is a need for an updated version they once again charge you for it rather than just sending you a free update.
Personally, I prefer perpetual-beta solutions than a stock solution which doesn't change over time. But that's IMO.
In the end, Apple has marketing and the fact that it's platforms really don't change much in it's favor. Windows has a lot of customization to it on the desktop end, and Android is quite a bit more open on the mobile end.
The hardware Apple has used for the most part until recently on the mobile end has been Samsung hardware, on the desktop end they've gone Intel CPUs of course.
And I still want to know who in their right mind makes a portable device out of glass?... given how many times I see people drop their phones, including myself... oh wait they want to make you pay for replacements. Nevermind hardware longevity.
That said, those who bash Apple without a clue of what's going on, or just to be "cool" is somewhat juvenile, however I doubt it's a stretch to say Apple products are overhyped, are far overprice for the hardware, and that it's software is functional but limited and lacks customization options. And that closed systems are bad for consumers when it comes to $$$/what you get.
