Sony announced sales of its second-generation PlayStation Portable have reached 1 million in two months time:
The second-generation PSP went on sale in Japan September 20 and hit the million mark November 22. That's two weeks faster than the original PSP took to sell a million units, Sony representatives said.
Compared to the original PSP, which went on sale in December 2004, the new model is 33 percent lighter and 19 percent thinner. It is also slightly cheaper and has a larger LCD screen. An optional digital TV tuner is also available that allows users to tune into Japan's free-to-air mobile digital TV broadcasts.
