>>Sure, true R&D is more expensive than simply re-packaging other deasigners technology.<<
Companies like Huawei and Samsung are hardware electronics companies. Apple takes that hardware and works out what people are going to do with it and how they are going to use it. That is software design and is nowhere as trivial as hardware thinkers like to make out.
Some people like the commenter above think that is trivial, but Apple establishing what they did in a very hostile marketplace is anything but trivial repackaging of others' ideas.
Apple has significantly defined the software and computing world as it is today. The old IT people are still hooked to IBM and then Microsoft who picked up the pieces and still resent what Apple achieved.
