I think this is awesome. The CEO of a $180 billion company meeting and greeting customers in a t-shirt on a public sidewalk. Whether or not you think the hype around each new Apple product is crazy, there is a genuine passion and enthusiasm here that just doesn't exist for basically any other company or product, and that passion exists both inside and outside the company.
Very well said indeed. That is really what separates apple (IMHO) from the others. I remember even SJ sometimes randomly pops up on an Apple Store to "mingle" with the crowds.
