THG checked out Acer's new Ferrari 4000 notebook which has a carbon fiber body. Here's a short snip from their review:

Like its previous model year, this Acer Ferrari comes equipped with an AMD 64-bit engine. But unlike sports cars, this Turion is scalable to the power needs of the driver and is also energy efficient. At full throttle it can run at 1.8 GHz, and it can pull back when there is no need for all the available horsepower. Our test system came with the ML-34. If the system is equipped with the ML-37, it can run at a top speed of 2.0GHz.
