There's a rule in the tech industry—making something out of carbon fiber makes it cooler. I don't care if it's a toilet plunger or a car hood, carbon fiber just sounds more interesting than "shiny plastic." Therefore, we aren't surprised to see that Asus is giving it a go in the carbon fiber notebook niche.
A few other folks have gone this route, but Asus seems to have hit a sweet spot. The V6V isn't too ostentatious. It's got a nice Pentium M-based chipset, and it's acceptably light—a 15" screen at 5.5 pounds—to warrant the carbon fiber.
