They do have the ability to buy which devices they see fit. That is the step that everyone neglects when making the above point. =)

So, you think that I can't use iPhone as a hammer, because I can do that with a Samsung? :)

Sorry, few countries agree with the claim I made - by investigating the lack of ability to have different app stores on iPhone, usually rights of the users triumph rights of the producer (at least in Europe, US is a different beast).

>Apple just produces them, users should have ability to use the devices as they see fit.

They have the ability to buy the device they see fit (Apple, Google, Samsung, whatever) -- they don't have the right to dictate other terms to individual brands.

The ability to dictate to the maker of the device how it shall be and who it should do business with and allow on its platform is not part of anti-trust law...
