My other favorites were Paul Buchheit and Peter Norvig, but it depends what you like. Here are my summaries:
David Lawee: Launch quickly! Google buys technology and people.
Sam Altman: How and when to get funding for your startup. Easy and detailed explanations.
Jack Sheridan: There are four important legal areas to consider for your startup: Who owns the company? Who owns the tech? Who controls the company? Who gets what in case of liquidity? Analysis of each of these.
Paul Graham: like the "Be Good" essay, but much more fun in-person
Greg McAdoo: What Sequoia looks for: big total market, company that defines a new category, rapid iteration, accumulated advantage.
DHH: "Step 2: Price!" In the context of the prior two talks, this one was explosive. Aggressively stated position that differs from the implicit philosophy of the rest of startup school, and a certain Web 2.0 scene in general.
Paul Buchheit: Inspirational. Leave your job if you feel drained. Left Intel for Google. Then left Google. What if Woz had stayed at HP?
Jeff Bezos: AWS is great! It's scales up and down elastically!
Arrington: "I genuinely look up to entrepeneurs." Roosevelt "man in the arena" quote. Engage in dialog with people who criticize you.
Marc Andreessen: Read "The Black Swan". High-level philosophy. Experiences in the first bubble. How to avoid mediocrity in growing your company.
Peter Norvig: Nerdy math/algorithms fun. "It's more agile to work with data than code."
The only talk I thought was mediocre was the legal one (good advice, but everything I got out of it could have been reduced to a few bullet points). Every other talk was fantastic.
