As proof that their new Extreme Sleeve for laptop computers is rugged and dependable, athletic gear company G-Form dropped a 13-inch MacBook Pro from a 20-foot balcony to demonstrate its durability. The case is designed for notebook "road warriors" who carry their laptop everywhere with them, and thus offers maximum protection against the drops, dings and other shocks that mobile computers are subjected to on a routine basis -- but can also guard the computer in case of a disastrous event.
