2001: Apple removed a long-standing “Start” menu from Mac OS. Existing customers were really angry about the menu being gone. There were hacks to bring the menu back.
2013: The menu is still not back, and everyone has forgotten about the menu. They love OS X for what it is/is-not, not what it was/was-not.
I’d say that even by 2004 the menu was forgotten. The good stuff being added to OS X blotted out the removal. Will we see the same timespans in Windows’ history?
