Day 4 of Apple e-book case: The meeting in Jeff Bezos' boathouse

"I'm not comfortable discussing the contents of that meeting."

That's what Russell Grandinetti, Amazon's (AMZN) vice president for Kindle content, said when asked in court Friday about a meeting he attended in Amazon CEO Jeff Bezos' Seattle boathouse on Sunday Jan. 24, 2010.

It was the only question in more than four hours of testimony that Grandinetti declined to answer.

Jan. 24 was a significant date in several respects. Amazon executives knew that Apple (AAPL) had scheduled a major product announcement for the following Wednesday.
