The last major consumer device intended to make mobile phone use easier brought us the unfortunate Bluetooth headset, so it’s great to see that the experienced electronics team at Rivet has introduced a system with interchangeable metal clips for easy wear. Their $14 GoClip seems well worth the promise of never losing “your phone or MP3 player again” (if only). As many city dwellers don’t have the opportunity to take advantage of products that can be affixed to car dashboards — although the company offers that too — the Horizontal Leather Bag and its plethora of pockets is a better choice for hauling daily devices.
