Other World Computing (OWC) today announced it has expanded the company’s line of laptop screen protectors (LSPs) to cover the new 15-inch and 17-inch aluminum PowerBooks. “Made from all-natural, top-grain cowhide leather, LSPs fit across a laptop’s track pad and/or keyboard to prevent the keyboard and button on the base of the laptop from coming in contact with, and leaving skin oils or permanent marks and indentations on, the laptop’s built in display.” Pricing starts at US$17.95.
