Sony PSP

The PSP Go (styled PSPgo or PSP go, model PSP-N1000)[7] is a version of the PlayStation Portable handheld video game console manufactured by Sony.[8][9][10][11][12] It was released on October 1, 2009 in American and European territories[1] and on November 1 in Japan. It was revealed prior to E3 2009 through Sony's Qore VOD service.[11] 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.[9]

Unlike previous PSP models, the PSP Go does not feature a UMD drive, but instead has 16GB of internal flash memory to store games, video, pictures, and other media.[12] This can be extended by up to 32GB with the use of a Memory Stick Micro (M2) flash card. Also unlike previous PSP models, the PSP Go's rechargeable battery is not removable or replaceable by the user. The unit is 43% lighter and 56% smaller than the original PSP-1000,[9] and 16% lighter and 35% smaller than the PSP-3000.[6] It has a 3.8" 480×272 LCD[13] (compared to the larger 4.3" 480×272 pixel LCD on previous PSP models).[14] 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.[15]
