We’ve a soft-spot for USB-connecting mini LCD displays – they’re a nifty way to get Photoshop toolbars, IM windows, Twitter apps and other windows off your main display but keep them readily visible – so we’re glad to see more options hitting the market. DoubleSight have three sub-displays to choose from, starting from the 7-inch DS-70U and then breaking into the hitherto unusual 9-inch segment with the DS-90U and DS-90UC.
