As part of its updates for PMA, Samsung on Saturday added two new U series pocket camcorders. The HMX-U15 and U20 together both have a new look that also hints at new features compared to the U10: either now shoots at 1080p and carries a built-in USB port to connect to a computer without a USB cable, much like a Flip. In a very rare move for the class, the U20 also brings 3X optical zoom to close in without sacrificing image quality.
