I’m not sure exactly how he found this balance. If you ever give presentations, go check out his slides and copy whatever it is he is doing, even if you aren’t interested in making zillions writing Mac software.
If you’re interested in hearing what he adds to his written points, are into the whole Podcast thing, and don’t mind spending 90 minutes listening to him, he has recorded his talk and made it available.
