Acer goes from the brilliant red design of the Acer Ferrari 3000 to a more conservative but just as sleek black checkered design. It retains some of the cool-looking red streaks along the side and front edge of the notebook, and yes, the yellow prancing horse emblem still graces the center of the notebook. The cover is made from carbon fiber, which is stronger and lighter than aluminum. (Acer uses it only in its Ferrari line.) The interior of the Ferrari 4000 has a rubberized coating, perhaps emulating the look of Formula One tires. The keyboard has an ergonomic smile contour to it, which is okay for typing but takes a few minutes to get used to. The only real design complaint we have is that the mouse buttons are a bit noisy when pressed.
