Pocket projectors don’t come more compact than the Acer C20. It’s small enough to fit in a jacket pocket and weighs a mere 168g. The features list is impressive, too, with mini-HDMI and D-SUB inputs, a microSD slot and a rechargeable l.410mAh lithium-ion battery. The problem fortheC20 is that it isn’t very practical. The brightness rating for this DLP-based projector is just 20 lumens, which means under standard office lighting you’ll only be able to project its 854 x 480 picture at a screen size of 24in before brightness tails off. In addition, the picture distorts noticeably in the top-right corner and focus is soft at the extremities of the image. If the price were lower, it might make a decent smartphone or netbook companion, but as it stands it’s far too expensive.
