I've heard a lot about how great Audrey is as a smart remote (e.g for my Audiotron) but when I went to ebay and saw the description, I didn't really get it -- is the touchscreen tied in by wireless, or do you have to plug it into a separate usb wireless bridge. If you need to plug into a wireless bridge, how can this be portable enough to make any sense? Is there some kind of tiny wireless card (like a pcmcia card) that you add to the audrey and make it wireless? If not, what am I missing? How do people use these things?
