We didn't get to meet him, and considering the huge difficulty he has just getting around and communicating, I don't think many people did. He was hustled offstage quite quickly. The appearance seemed to exhaust him.

His speech was largely pre-assembled on his computer, with an accompanying slide presentation, although he sometimes picked different pre-written segments out of a storehouse of them, depending on what he wanted to say.

Answers to questions at the end, taken from written ones passed up, were composed on the fly. This often took several minutes of the audience patiently waiting as he skillfully flipped through his computer to construct wholly-original sentences, often with a wicked sense of humor. Wish I had a transcript, or a better memory.
