Scanning the comments, there's a fair bit of argument about lean vs. cheap and about whether Horowitz is agreeing or disagreeing with the "lean" approach. Afaik, all he's saying is "it depends". There may be situations e.g., if your competition is cash poor and you are cash rich, where the "fat startup" approach makes sense. It doesn't seem like he's fundamentally arguing for or against "lean" - just that a lean or fat stance only makes sense in specific contexts.
