I have to agree, and a lot of the other responses in this thread are disheartening/annoying.
The biggest thing Steve Jobs brought to Apple was to build a culture that supported his vision. Apple as a whole is focused on the mold that Steve brought back with him. Tim Cook has been the avatar and excellence in this image on the operations/production side. A company that has AMAZING profit margins on it's products due to the operational efforts to buying up needed parts ahead of time, etc. I suspect Jonathan Ive will be able to continue the design esthetic. Apple is a company running on all cylinders to deliver focused products. This differs greatly from the Apple before Job's returned. Will the focus erode? Possibly, maybe some of the perfection will be lost, but there is a much stronger base in plance than ANY other company in the valley in the last 20+ years.
Compare this with Microsoft when Bill Gates steped down. While, I personally feel that MSFT has made some positive steps in mobile with the Nokia partnership and WinPhone 7 doesn't suck, the company wasn't focused. Each department was kinda doing it's own thing. Ballmer was left to try and build something out of a lot of disparite pieces. As such, MSFT, as a stock, has basically flatlined for 10+ years.
I think it is safe to say, outside of Hewlett & Packard (more recently) and the Fairchild Eight, no single person has been more influential on the Bay Area technology scene in my lifetime (born and raised here). I will go one step further, and state, I don't see any of the current "elite" Paige/Brin/Zuck/Ellison(he's still around and strong) contributing anywhere as much.
Steve, like Bill and Dave, Gordon Moore (etal), are in a class of their own.
I've loved/hated AAPL products over the years, but Steve has been nothing but a gem for the valley.
