The PSP Go (stylized PSPgo or PSP go, model PSP-N1000) 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. It was revealed prior to E3 2009 through Sony's Qore VOD service. 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. On April 20, 2011 announced that the PSP Go would be discontinued so that they may concentrate on the NGP.  Sony later said that only the European and Japanese versions were being cut, and that the console would still be available in the USA.

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. This can be extended by up to 32 GB 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, 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.

I heard they where making a new one with a touch screen an such.

I think one of the problems was that you couldn't play ISOs/Pirated games/Homebrews on it. You could hack the oledr PSP easily.
