This upcoming book about Steve Jobs during the NeXT years sounds really good, via John Gruber:

With unprecedented access to unbroadcast footage of Jobs in NeXT meetings, private company documents, and interviews with his closest colleagues, Cain offers the definitive account of how failure transformed a brash wunderkind into a true business genius.

I got my first Mac during those years. Steve was legendary, NeXT machines felt almost mythical, and I’m not sure I ever considered that he would return to Apple. What an extraordinary life.
