Bluetooth love
Its important to state that this is not theoretical; it can all be done and if no-one does it then I will.
Great idea from Alex Eckermann on using the Bluetooth 4 chip in more-recent Apple devices to figure out which device you’re actually using and cut down on excess duplicate notifications. i’m in complete agreement here, I really don’t need five devices beeping whenever someone mentions me on Twitter and this seems like a very clever and simple solution.
