Indeed,<p>I would recommend Game Theory Evolving by Herb Ginitis. Human beings have a <i>strong</i>, repeat <i>strong</i> bias toward retaliating to maintain fairness. Varies culturally to only a small extent.<p>Anything that raises the <i>possibility</i> that you'll just be taking off with their money is going to create a strong reaction.<p>The mistake was taking pre-orders. Never take pre-orders if you're to delay shipping. You'll piss Max (and me, and everyone) off.<p>I am not twenty-something, btw
