The PSP Go is a version of the PlayStation Portable handheld game console manufactured by Sony. It was released on October 1, 2009 in American and European territories and on November 1 in Japan. Although its design is significantly different from other PSPs, it is not intended to replace the PSP 3000, which Sony will continue to manufacture, sell, and support.
Unlike previous PSP models, the PSP Go does not feature a UMD drive, but instead has 16 GB of internal flash memory to store games, video, pictures, and other media. The unit is 43% lighter and 56% smaller than the original PSP-1000, and 16% lighter and 35% smaller than the PSP-3000. It has a 3.8" 480 × 272 LCD (compared to the larger 4.3" 480 × 272 pixel LCD on previous PSP models). The screen slides up to reveal the main controls. The overall shape and sliding mechanism are similar to that of Sony's mylo COM-2 internet device.
