Oh, how I love the Newton community. When the various message pads shipped, they came with instructive VHS tapes (yes, VHS) that described just how they should be used. Some enterprising Newton user has taken the time to encode several of the tapes (specifically the Original Message Pad, the MessagePad 110 and Newton OS 2.0) to H.264, and made them available as a video podcast [iTunes link
]. Nice! Also included is a video on using the Newton OS on 3rd party hardware.
