If you haven't already read the Steve Jobs biography by Walter Isaacson - either as a hefty hardback book or an ebook - you may be interested to learn that the paperback version will be out this September.

This seems to have been quite a delay between hardback and paperback versions. The reason for the delay is unclear.

One thing is immediately apparent though, the photograph on the front of the book shows a much younger Steve Jobs, though in the same thumb-on-chin pose as before. The photograph was taken by Norman Seeff in 1984 according to AllThingsD's report.

We wonder if the choice of picture, addressing Jobs as a young man is designed to appeal to a different age group of reader.

With the first of two Steve Jobs movies due out in the next few months, we expect that the co-founder of Apple's story will be opened up to a whole new audience.

Unfortunately, having read the book, we're not sure that the young Steve Jobs is such an aspirational character.
