The Laptop, Circa 1968 120

But Computerworld reports on Anderson Jacobson's 75-pound Teletype-terminal-in-a-case, an early attempt to let folks compute from anywhere.

USAF reliability efforts. (Score:5, Insightful)
From the mid-1960s to the mid-1980s, the USAF put a huge amount of effort into making electronics more reliable, with considerable success. One of their more interesting efforts involved marking a few percent of the Air Force's inventory of electronics boxes with a sticker instructing users that the unit was part of the USAF's Reliability Program, and if it broke, it was to be replaced as a unit, not fixed in the field. The broken unit was to be sent back to a lab (at Wright-Patterson AFB, I think) for analysis.
At the lab, the unit was tested and the failing component(s) found. The, the failing component was disassembled and analyzed. This involved opening up transistor cans and looking at the component under a microscope, and if necessary, an electron microscope. The USAF was trying to understand why components failed in the field. Did a "hermetic" seal leak? Was a bonding wire badly soldered to a pad? Was something mispositioned? Was the transistor substrate damaged?
Results were published in Aviation Week. With enlarged pictures of the defect. Part numbers and names of vendors were given. The USAF deliberately did this to apply pain to vendors.
Over time, parts got much better. By the 1980s, though, the USAF wasn't buying a big enough fraction of the output of the electronics industry to get much attention, much to the annoyance of senior USAF types.
