Ah, the circle of life. Thirty years ago, Bill Gates visited Nokia to check out its latest MikroMikko personal computer — competition to IBM's own line of (Microsoft-powered) PCs in the ‘80s. No one could have guessed back then that IBM would bow out of the PC hardware market and that Microsoft would buy Nokia's massive devices and services unit decades later. There is one thing we should have seen coming, however: those large-frame glasses were always destined to fall out of style.
