In almost my entire working career, I've used Apple products and Steve Jobs has always been there, well except for that span where the board kicked him out (what were they thinking?). It's hard to believe that Steve Jobs will not be around to introduce a new product.
When I was growing up, I couldn't wait for the latest release of my favorite band. It was a time of anticipation and excitement. As new record releases became less import and music was leaked, Steve Jobs slowly crept into that role of creating excitement. The speculation on the latest iPhone was building for months and just yesterday the iPhone 4GS was revealed. The talk leading up to it, could only rival that of the next Led Zeppelin record in the 1970's.
Steve was probably one of the most important people of past 25 years and yes he left the world way too young at 56. He was here and he did make a difference and I certainly benefited from it.
