My first class I've had to teach since getting my MBA. VGA dongle hooked me right in and nothing to do but watch it fire up the old projector immediately. No searching for resolution, nothing of the sort. Perfection. I was using the little white apple remote that came with my iMac to advance my Keynote slides. Very laggy and not very exact. I'm going to have to go back to using my old USB gizmo to advance next time.
