What other things were terrible about the biography? It's my favorite biography of all time. I'd love to know better what important parts were left out.
I was looking for deeper analysis of what made Steve Jobs' tick, and how he approached building products. Walter Isaacson didn't have a technological understanding of Apple's products of the time, so I found his history pretty superficial.
I learned much more about Steve Jobs approach from listening to the interviews he did over the years.
