The Toughbook uses a magnesium alloy case claimed to have 20 times the tensile strength of the plastic in most other notebooks. A magnesium alloy frame protects the 12.1 inch LCD. It also features a special steel enclosure for the hard drive to enable it to withstand shock. All in all, a fairly tough package.
But tough doesn't come particularly cheap; the Toughbook weighs in at $4,799 with a 500 MHz PIII. But if you're looking for a laptop that won't break down if you use it to say, beat someone up, it sounds like the Toughbook might fit the bill.
