DisplayLink USB Video Solution is now Mac Ready (But Why?)

For DisplayLink, the big news at MacWorld was the announcement of their Mac-compartible Virtual Graphics Card (VGC) software. A beta version of the VGC was on display at the company's booth on the show floor. Basically, existing DisplayLink-powered USB monitors, notebook docks and video cards will soon be able to extend display on up to four displays for Mac mini, MacBook and iMac users. Except for Mac mini that is limited to one DVI, the other Macs already have its own screen and already provide an additional video output. It's really for people who need a third or a fourth monitor that DisplayLink matters. Then again, if DisplayLink makes a WUSB video card, then there will be unseen opportunities and applications.
