Gizmodo points out that the "wireless" element of Iogear's Wireless USB hub and dongle doesn't wash: The wireless part is the missing USB or network cable, but you still have to use cables to connect your USB devices to the hub, which itself requires AC power. Gizmodo found problems in setting up the Iogear system, which runs $200, and thought performance was poor. Separate drivers were required for the dongle and the hub.
These criticisms are all pretty justified. Ultrawideband (UWB) networking in the form of Wireless USB can't shine until UWB radios and drivers are installed at the factory on laptops and peripherals. UWB chip costs are already dropping, and it's likely that $500-and-higher electronics, like cameras and camcorders, will sport UWB by next year, as will computers. When you can associate a UWB device directly with your computer, no hub required, its utility will be much higher.
I've been waiting for that day to come for, oh, five years now. Maybe in 2008! (A technology reporter has to have constant optimism mixed with a jaded outlook.)
