So far, the best set of notes from Saturday's annual meeting, in Omaha, of Berkshire Hathway shareholders I have seen is this one from Motley Fool.
[UPDATE 5/7/13: This set, by Peter Boodell, is even better. It is nearly a transcript.]
I also found the NYT's set, here, helpful.
There is a good set from Morningstar, too. I don't think a subscription is required (but if so, it is a good excuse to sign up for Morningstar, which is useful).
That's probably enough, but for those wanting every tidbit, this set from the FT is worthy, and Charlie Munger did a long CNBC interview with Becky Quick.
I often go to the meeting, but skipped it this year.
