There is no shortage of mini-USB monitors, especially in Japan and Korea. In USA, Korean company Nanovision’s MIMO-series seems to have dominated the market albeit small and niche with its bus-powered but relatively pedestrian 7″ USB monitor (UM-710).

Its more talented sibling – the UM-740 – gets much more interesting with touchscreen capability and integrated webcam. If you drop $30 on top of the $199.99 MSRP, you get full Mac support. Unfortunately, the MIMO UM-740 sold out almost as soon as it went on sale in February due to overwhelming demand (or severely limited supply). But fear not, the USB touchscreen mini-monitor is once again available. Grab one before it goes out of stock again; that is if you need the extra 800×480 pixels to play YouTube video full screen, or to put away your widgets, IM client, Gmail on a secondary display.
