Josh Lowensohn visited Apple:
A few blocks away from Apple’s bustling campus in Cupertino is a rather nondescript building. Inside is absolutely the last place on earth you’d want to be if you were an iPhone. It’s here where Apple subjects its newest models to the kinds of things they might run into in the real world: drops, pressure, twisting, tapping. Basically all the things that could turn your shiny gadget into a small pile of metal and glass.
The interesting thing is, that inside Apple, away from the glamorous marketing world, there are the same laboratories as everywhere else.
