Not a Steve Jobs fan, but recognize what he did for the industry.
If you read this forum from your HOME computer - thank Steve Jobs (and Steve Wozniak). They saw the potential for marketing a HOME computer in an age where computers were not yet in homes.
The Apple II was the start of it all. The IBM PC didn't come out for a couple of years later. Though the PC helped home computers become mainstream, the Apple (Lisa, Mac, etc.) helped make it easy for people to use.
However, IMHO I'll be more unhappy when Linus Torvalds passes away than Steve Jobs.
(I'll leave it up to the geeks to chime in on Linus' contributions to computers)
