Panasonic's Toughbook line hasn't only been impressing in extreme durability lately, but also in extreme weight-loss. Joining the 3.2-pound Tougbook C1, is the newest 12.1-inch Toughbook S9, which weighs just three pounds. And yes, Panny's claiming it's the lightest 12-incher with an optical drive, and our quick research seems to prove that claim right. Even more impressive is the power that's packed into the featherweight chassis -- it's got a Core i5-520M processor, 2GB of RAM, and a shock-mounted 320GB hard drive. Thought that Panasonic gave up the durability for that weightag
