Take the phrase "water resistant" with a grain of salt. I highly doubt this laptop would survive a full plunge in the swimming pool. The draining system protects the laptop's hard drive, motherboard and some other internal components from small amounts of liquids with a waterproof sheet draining system. Also included is impact proof protection up to 220 pounds. These laptops are only available in Japan right now, but expect to see the features heading our way soon.
