For those looking to maximize their off-road capabilities, the Itronix Hummer Laptop IX600 ($3,368 direct) plans to deliver—if you're willing to fork over the extra cash. Much like the vehicle, the Hummer laptop is equipped with an SUV-like chassis complete with the Hummer logo. It has a wide selection of connectivity options, including built-in GPS. The system is ideal if you're out in the field all day (think construction workers, architects, park rangers, field scientists, and so on), but for the average Joe who wants a cool car-theme laptop, the $2,000 Acer Ferrari 4000 is a much better deal.

The metal cover is designed to look like a Hummer's hood and comes in three colors: red, bright yellow, and pewter tin. We prefer the subtle red lines and carbon-fiber outfit on the Acer Ferrari's chassis to the chunky, in-your-face style of the Hummer. (Though, in all fairness, the Hummer SUV is seemingly all about being in your face.) Itronix is known for making notebooks for the military, so you can be sure that this one is made to withstand some abuse. The chassis is made entirely of magnesium alloy and feels much thicker than that of the Panasonic Toughbook W4. A nice design feature is that the notebook has a handle at the back so you can carry it like a briefcase. According to Itronix, the Hummer laptop can withstand drops (from 30 inches), strong vibrations, and extreme temperatures. It also has a spill-proof keyboard. We wouldn't recommend subjecting a $3,368 laptop to any of these hazards, but having that peace of mind is always a plus.

Despite the relatively diminutive 12.1-inch screen, the 6.7 pound system isn't easy on the arms. Other systems with 12-inch screens typically weigh half as much, such as the 3.2-pound Lenovo ThinkPad X41. The Hummer's screen is designed for outdoor viewing, and we noticed that images looked washed out when you take it indoors. The full-size keyboard was comfortable to type on, but the touchpad isn't as wide as that of the Ferrari 4000. A keyboard task light pops open above the screen for dark conditions.
