A retrospective on Switcher, the 1984 Mac utility that let users switch between applications, prompted discussion about how much original engineering insight could go into tiny programs and how a $50,000 figure from that era would be worth over $320,000 today. Readers also compared it with early IBM PC TSR utilities like Memory Shift and Borland Sidekick, while trading anecdotes about old-school debugging and the humbling craft of early software.
