There have already been a few 15-inch Ultrabooks that have pushed the very limits of the thin-and-light category. Still, LG wants its turn at bending the rules. Its new U560 packs a 15.6-inch display and an optical drive that, together, contribute to the PC's 4.3-pound weight and 0.82-inch thickness -- really, it's a traditional laptop in a slimmer than usual package. Not that we'll complain too much when it involves an IPS-based LCD, a 1.8GHz Core i5, dedicated graphics (a support page suggests NVIDIA) and both a spinning hard disk as well as solid-state storage. The U560's launch is limited to South Korea so far, although we wouldn't be surprised to see Europe and other territories get their turn.
