Despite their slim and delicate appearance, Apple’s iDevices are pretty tough. I have dropped my iPad mini from the top of the fridge onto a tiled floor with no real damage – just a dented corner. In fact, in the five years that I have owned iDevices, I have broken one screen, and that was an iPod touch in a front jeans pocket which got completely wrecked in a drunken bike crash (I think that’s what happened, anyway – I don’t really remember).
Which is to say, the majority of mollycoddling we bestow on our iPhones and iPads is unnecessary. The only thing which really needs protection is the screen.
