Belkin introduces a $60 WI-Fi adapter/router designed for travels: The compact 802.11g device will ship at the end of August, and is designed to share connections. It can be used as either a Wi-Fi adapter or as a gateway. This joins an increasingly large family of compact routers, but it's one of the least expensive. One step better would be USB as an option for power or even batteries to avoid an AC adapter altogether.
Glenn, wouldn't powering the wireless router by USB defeat the purpose? That would essentially tether the unit to your computer.
USB power? How exactly would that be a benefit? If I have this right, using USB power would mean you'd have one end of the router plugged into the hard Ethernet line, and the other end of the router plugged into your laptop for power. That seems to make the router useless, as you are now tethered to the router, when the whole idea was to be wireless. Apple has it right with the AirPort Express -- AC plug right on the unit, small and folds up, and no external power brick or wall wart needed. I cannot understand how USB power would be a benefit for these kinds of devices.
D-Link has a similar product priced at about $40 (http://www.dlink.com/products/?pid=346), the USB power comes into play when you use it as a wireless client.
