I may have a requirement within the next year for a ruggedised laptop. I've looked at the Panasonic Toughbooks, but I really want a Mac. What can be done for the Apple laptops to make them resistant to moisture, high altitudes, and extreme temperatures? The laptop must survive a rainstorm of about 1-inch per hour for 30 minutes. The battery compartment, keyboard, and connection ports would all need to be water-resistant. The laptop must resist humidity up to 95%, operating temperatures up to 140 degrees Fahrenheit for 10 minutes, and non-operating temperatures up to 160 degrees Fahrenheit for five hours. The laptop must also operate at altitudes up to 15,000 feet. What is the recommended solution?
