I am writing this on my iPhone on the train, thanks to Apple. Smartphones existed before iPhone, but it was iPhone that made everyone (ok Tevye, almost everyone!) want one. Same with tablets - iPad turned tablet computers from a tiny niche market to a mainstream product. The iPod changed the way we listen to music forever. iMacs made computers a thing of beauty. Steve Jobs, quite literally, changed the world. Whether or not you own an Apple product, you almost certainly communicate and use computers differently because of the technology that Apple developed or popularised.
I am a huge fan of Apple. Partly because their product design is so immaculate; partly because everything "just works". Who would have thought a decade or so ago when Microsoft appeared to be taking over the computing world that Apple computers would ever become more than a niche product, if the company managed to survive at all? Reenter Steve Jobs for his second stint as head of Apple. And today Apple is ... what? ... the second largest company in the world? (I don't have time to check!). I also heard on the radio the other day that a survey reckoned it the second most iconic brand in the world. Quite some combination that!
So RIP Steve Jobs. Your legacy lives on.
