That sounds like a monsterous task your proposing. But I think it would be valuable expecially to new comers to Amiga.
"Ok, I've heard of Amiga and it sounds interesting. So where do I start, what hardware do I need and what are the programs I need to get loaded?"
Sounds like your book could help fill the need. And of course you can't forget to reference places like Amiga.org :-)
