Willow Design has released five new cases specifically designed for the new 17-inch PowerBook. The three slipcases and two traditional briefcase style cases range from an ultra-thin slipcase designed to be slipped into other bags to an extremely protective two level case with tons of peripheral storage. They are constructed of polyester and nylon fabric with 1/2-inch foam protection throughout, reinforced by combinations of corrugated plastic, high-density polyethylene on the handle side and hardboard on the bottom. Prices range from US$64 to $169.
