Sony\’s new X505 is the world\’s slimmest laptop at only 9.7mm thick. It\’s made of carbon fiber (the same stuff used in race cars) and nickel carbon to reduce weight. It has a sloping design, reminiscent of an empty 3-ring binder. There\’s no CD-ROM, but it\’s decked out with a lot of other features: ethernet, modem, firewire, USB and PC card slot.
