Things I've learned in San Francisco:
There are physicians who have never used a computer before. Ever. Many who claim basic skill in order to get into an intermediate course are faking it.
Børn Shoes are rather comfortable when you're on your feet all day proctoring courses, then walking up and down hills at night.
Physcians will use any opportunity the have to check their e-mail.
Anything that can go wrong in a computer training class will (unintended shutdowns, accidental disconnection of power/networking cords, etc).
