Design is really an important part of the Steve Jobs story, and it isn't one that a lot of people understand. Some do. So, although it isn't an understanding that comes quickly or easily--it's more like riding a bicycle, you have to learn it by doing and falling over sometimes--it is one worth understanding.
So, here's a NYTimes article on Jobs and design, and here's the text of Jobs' Standford address from 2005, where he discusses calligraphy, and lastly here is one about Jobs and what is not there in terms of design, called ma, or what is not there, which I think is a vital part of the picture (the author of that article, Jeff Yang, explains it well).
Everything is design, design is everything.
