Belkin's CableFree USB Hub and Dongle hit retail shelves this spring. The key word is "CableFree", this hub and dongle utilize UWB, or Ultra-wideband technology which in this case is USB speeds without wires. Belkin claims that this UWB implementation is 100 times faster than anemic Bluetooth, which makes it superb for kickin' out large datastreams through thin air. The Belkin CableFree USB Hub and Dongle will retail for $129.99.
