Samsung didn't kill Sony. Sony died because of old age.
Samsung started off by copying/following Apple. They still do. Retail stores? Apple is one of the few tech companies that pulled it off successfully. You don't see a Toshiba store, Dell store, etc. Same with store within a store stuff. Apple wasn't the first, but they are one of the few that make it work successfully. Without Apple, Samsung will die.
Samsung has been around since 1938. Pretty sure they will be fine without Apple.
