For about the price of a docking station, you could just skip the whole docking part altogether, assuming Kensington’s new Wireless USB Docking Station works as advertised.
The device costs $229.99 and features a DVI port, five USB 2.0 ports, and an audio out jack. It can handle monitors up to 1680×1050.
It appears to be simple enough to operate, too. You’ve just got to be within 15 feet of the device and your computer either has to have a built-in wireless USB host device or you’ll have to purchase one, like this $75 one from IOGEAR. That might be a deal-killer right there. Newer notebooks should be coming out with the wireless USB stack built-in, though.
