Bluetooth adapters are not exactly the bulkiest things to carry around but nevertheless those sticks protruding out of your laptops are never very convenient. So Newton Peripherals has announced the Mogo Dapter; the world's smallest Bluetooth adapter. Its just the size of a finger nail and if you ask me it even looks like one. The greatest advantage with something as small as this is that you can easily plug it into any USB port set it up and forget about it: as it is so small it doesn't protrude out like normal other adapters usually do.

From the official site:

MoGo Dapter is finger-nail sized Bluetooth Adapter that plugs into any laptop or tablet USB port. The Dapter uses advanced technologies - Bluetooth standard v2.0 +EDR and USB 2.0 - to provide you with quicker connection times, enhanced voice and multimedia quality, greater Wi-Fi environments, and up to three-times-faster data-transfer speeds than v1.2 Adapters.
