Already known for ultraportables, LG took a more direct shot at the ultrabook category Monday with a new addition to the Xnote line. The Z330 carries a 13-inch screen and a tapered, silver and black design reminiscent of a cross between the MacBook Air and MacBook Pro. LG claims the system is lighter, at under 2.7 pounds, and slightly thinner, at 0.6 inches.
