The author, Cringely, mentions that he helped write the business plan for Illustrator, Adobe Systems’ first consumer product. But you never get to see the business plans of super successful products -- that's what I'd like to see.

The one exception is "The Autodesk File" by Autodesk founder John Walker:

It has the genuine documents from Autodesk's early years including business plans, finances, stock discussions, etc. I'm actually amazed that he did release it.
