This book strikes the right balance between airy New-Economy titles with no practical advice and dry business-school tomes which mire you in unnecessary detail. It's considerably better (to my taste, anyway) than the existing e-commerce "HOWTO"s, because it gives you the practical advice you need to go from literally nothing to knowing enough to start seriously thinking about leaving your job.
Obviously, no one book can do everything, but having some little experience of the venture capital business, I'd say that someone who'd read this book from cover to cover would probably be able to talk a decent game with first-stage capital providers (always assuming that their actual business idea was any good, of course). The legal advice is sound, the technical sections are pitched at the right level (ie; aspiring CEO), and the book is packed with hints and tips about the easy mistakes to make. I'd advise anyone who's worrying that they might be missing the boat to buy this book, read it, and then try to come up with a good idea.
It also has the benefit of being well-written and easy to read without being patronising, which anyone who has read a lot of business books will be thankful for.
