AMD's new Fusion APUs That's plenty of horsepower for a system aimed at the sub-$400 market ($398 starting price), which practically puts the machine in direct competition with the various 11.6-inch Fusion systems we've seen. There's not much else to tell about the C655D. It weighs about 5.5 pounds, gets about six hours of battery life, supports up to 4GB of RAM, and ships with 320GB of storage as well as a DVD drive. No word on availability yet, but it should begin shipping soon enough
