Leave it to KFC to create a way to use your gadgets with greasy hands

Unless you have copious amounts of napkins and the patience to use them every few seconds, then eating greasy fast food and playing on your smartphone or tablet are two things that can’t be done simultaneously. Or can they? Some KFC restaurants in Germany have started a limited trial run of food trays that come with built-in keyboards that connect to your device over Bluetooth, thus allowing you to continue using the device without getting grease on it.
