Very simple...
- Apple locks you into their system and won't allow you to customize it.
- Apple over charges for every thing they have.
- Apple will not allow you to use anything unless it is in "their store"
- Apple will not allow you to buy accessories at a reasonable price.
In 1982 I had a Mac, 3 Apple II, 2 Apple II GS computers. Every time I wanted to add more memory or some other accessory, they wanted Rip Off prices. $350 minimum for a memory expansion card when I could get one for an Intel 286/386 based machine for $35.
I had been a very solid Apple supporter since the day they released their first one.... but their refusal to allow anyone else to provide reasonable cost accessories, or to price their products at a reasonable price, lost me in their camp.
I put an advert in the local newspaper and got rid of every piece of Apple crapola that I had.... Used, all of that was and still it brought me $3,000 because of demand for "reasonable prices" for Apple stuff.
I have never allowed an Apple product to touch my doorstep since and it will be a cold day in hell before one ever does.
