Whatever one might have in mind regarding Apple, he as a visionary man will leave a big hole.
I was working with macs, was teaching the use of macs, had a mac myself for more than 10 years and saw Steve Jobs doing so many interesting things. Todays MacOS X wouldn't exist, if he did not found neXt.
And it is too young to die, no matter if your name is Steve Jobs or any other. 56 just is too young.
