wants to solve that problem by providing a USB adapter that you can leave in your computer pretty much all the time. The Dapter is a small rounded bump that barely protrudes from your laptop; you can plug it in and forget about it. It supports Bluetooth 2.0 EDR, the top Bluetooth standard at the moment, and is compatible with both Mac and Windows. And weighing in at just .09 oz, with dimensions of .4″ x .73″ x .37″, you’ll barely even notice it’s there. It’ll run you just $50, which is commensurate with most Bluetooth adapters.
