This is by far the best book of the genre that I've come across.While I have also recently enjoyed reading The Lean Startup, by Eric Ries - Rob's book is by far the more practical, and useful, for the individual developer seeking to launch something.If you have been considering one other book, The $100 Startup, by Chris Guillebeau,  Trust me, you will find "Start Small, Stay Small" a much better value for your money.
