Who invented what?
I can name a whole lot of names of famous names who have worked and contributed at Apple. People who are well-known in the industry apart from Apple. Apple understood their ideas and employed them and they were happy to contribute their ideas because Apple was prepared to take the risk on what were unknown ideas at the time, even ideas that were contrary to industry-accepted wisdom.
When it comes to Samsung, I cannot think of a single name, or really any contributions Samsung have made to computing research.
I don't really like Microsoft or IBM, but at least I can think of names and significant contributions they have made. Google also. But Samsung a big ?.
