I recall a point by Jobs et al. wherein the original case for GUI drop-down menus was motivated by a clear desire for discoverability, versus the arcane keyboard shortcuts of the IBM applications of the time. That stuck with me for a long time, and I remembered it when MacOS and iOS first began departing from that philosophy with their modern looks. I would say Jony Ive contributed a lot to this transition from user-friendliness to design-led, form-over-function.
