I remember seeing the first Apple microcomputer, and realising the guys who built it were a step ahead of anyone else. What is amazing is how Apple has kept that step ahead for 40 years, and that is no accident. Many people claim to "change the world", Steve Jobs was one of the select band who did - and in a positive way.
What is astounding is that he has been making technology easy to use for all those 40 years, and many of his competitors still don't "get" it!
(Update ...this does not mean Mr Jobs - like any genius - did not have flaws, or was not difficult to work with, of course)
