Consolidated Jacks from Apple...
It's well-known that Apple has a thing for eliminating physical buttons wherever they possibly can (see their buttonless elevator for one extreme example), but now they're turning their attention toward eliminating physical cable jacks. A recent patent filing combines the headphone and microphone jacks into one - though I'm not sure how this is any different from the existing mic-and-headphone combo on iPhones. In any case, it's a fine idea: Apple is quite correct that every jack in a device "breaches the barrier that protects components inside the housing" - so reducing them makes a more robust, damage-proof device. Ideally, the jack wouldn't even be a hole, but instead something more like their mag-safe connectors... Oh well, progress is progress!
