I vaguely remember going to a presentation by a NeXT engineer about an enterprise objects/webobjects project they did for the USPS where they photograph every letter passing by on a high-speed conveyor, use realtime processing to get the zip code and then sort it onto the correct belt
Yeah, Rob Blessin of Black Hole Computing bought the Cubes and Slabs (sans hard drives) when the CIA moved on to white hardware. At the time, I didn't have the need/funds for a spare, but did grab a NeXT-branded Canon inkjet printer.
