@tomxcd In 1999 my university group was evaluating replacements for our aging, low-end Unix workstation for undergraduate teaching. None of the existing Unix workstation vendors could match the price and performance of name-brand PCs running Linux (not even the ones that basically used PC hardware), so we switched. As part of the switch, my office machine changed from an SGI Indy to a PC running Linux (although I kept the Indy running in a corner for years afterward, for reasons).
