Rewatching the classic Trek episode “The Conscience of the King,” which features a Shakespearean acting troupe.

In one scene, McCoy writes a report on a wedge proto-iPad…

…but in the very next scene Kirk scrawls on a piece of paper.

This episode also features characters doing computer searches, using an exposition-friendly voice interface to call up photographs of individuals and compare their biographies, which must have seemed very futuristic back in 1966.
