Style that works. Weighing in at less than a pound, the Arc Keyboard is easy to move from room to room throughout the house and its comfortable domed keyset allows hands to comfortably rest in place while typing, whether users are kicking back on the couch or typing away on the kitchen counter. It includes a snap-in Nano transceiver that is so small it can remain plugged in to the computer at all times, or can be magnetically snapped in the bottom of the keyboard for storage. With its unique, compact design, the Arc Keyboard becomes a functional and stylish part of any living space. It features a stowable nano transceiver, 2.4 GHz wireless, on-off function, and battery status indicator.
