Although I'm not particularly a fan of Steve Jobs himself, I just wanted to say : you cannot lead a company to such a success with "chance". The guy was a really good manager, and this doesn't necessarily mean a "cool guy". He was known for his difficult character, but it's sometimes what works.
I only understood the genius behind Apple when I got my first apple computer (a current macbook pro), although it's half white half "evil" cause of the addiction and the consumer lock you can feel growing in you when you get into a product, and it's all good as long as you accept to enter it, and to be honest it's not like it changed my life, or if it did, it did in a good way. In the end of the day, I still feel like using a personal computer, the only difference is that it feels smoother and more stable than my crappy previous ASUS. I mean, people always say Apple didn't invent anything, they just recycle ideas and add some good marketing on top of it, but that's not true. Both Microsoft and Apple (and IBM, and so on) have their share of paternity in many things that changed our life wether we like it or not. But what other company can say "ok guys, in a few days, when you take a picture in any of your devices, it will be instantly synchronized in all your other devices, we take care of the technical side of this". People don't understand what's behind this, the softwares and the coordination of their developments, the parks of servers, the long time strategy (and they proved to be pretty efficient), the HUGE technical challenge etc. Luck is only a tiny part of all of it. Good or bad, depends on the opinion, but Apple IS a pretty unique company.
