Apple fans can ramble all they want about how everything is simple and easy in Apple products, but eventually products get complicated. That's why Macs grew those awful hidden bits of complexity called Context Menus and you find them all over in OS X apps now, and that's why features like multitasking on iOS are hidden behind increasingly arcane and obscure actions. Double-tap the home button? Shake to undo? Yeah, defend that stuff all you want: Sometimes good UX design still involves compromises.
