Had a nice conversation with Tim Cook today. Discussed my opinion that a larger buyback should be done now. We plan to speak again shortly.

We're not about liquidating companies, but if you do that, why is that terrible? We're not blowing up the factories. The person who buys it should be able to make the asset more productive.
