Toshiba's 14" USB Mobile LCD Monitor
 

While notebook hardware has steadily improved over the years, outside of the recent MacBook Pro with Retina Display there haven't really been any moves forward in improving desktop real estate in some time. In fact, for productivity-oriented users this continues to be a major reason for sticking with a desktop setup (if not a desktop system): more monitors, more space to work in. This fact of life has resulted in a bit of a niche market in the form of small, USB-powered screens.
