I easily have 3-4 production tapes, still new in the box and I'm pretty sure I have some first runs for proofing before it went into production.
Lots of great information in that video that's still relevant and useful today.
When I typed out the script I had a keyboard that was really loud, that is every time I hit a key it would make a loud *clack* sound. Some days it would sound like a machine gun was going off in my office and I'm confident I drove my co-workers up the wall.
I miss that keyboard just because of the sound but I love my MS full size ergo keyboards...
