I don't think Steve Jobs can take credit for MP3 players existing. If people weren't using Ipods and Iphones, they would be using Diamond Rios and Blackberrys that were pretty similar.
I'm not talking about MP3 players really, I'm talking about all of the references to touch displays, wearable computers, solid-state drives, high fidelity ebooks, sales of digital media, etc. Apple didn't really invent these things, but they certainly played a big role in making them ubiquitous.
