I've always thought Bluetooth was obscenely high priced, and this device reinforces that: for an initial price of US$76 (which should go down if folks start buying) you get 802.11b/g, where the cheapest Bluetooth device with a similar interface is US$60, and Bluetooth is far less capable than 802.11 in terms of range, bandwidth, interoperability, etc.
Well, who's gonna buy one and let us know how it works?
