The PSP Go (model PSP-N1000) was released on October 1, 2009, in North American and European territories, and on October 31 in Japan. It was revealed prior to E3 2009 through Sony's Qore video on demand service. Its design is significantly different from other PSP models.
The unit is 43% lighter and 56% smaller than the original PSP-1000, and 16% lighter and 35% smaller than the PSP-3000. Its rechargeable battery is not intended to be removed by the user. It has a 3.8-inch (97 mm) 480 × 272 pixel LCD screen, which slides up to reveal the main controls. The overall shape and sliding mechanism are similar to those of Sony's mylo COM-2 Internet device.
The PSP Go features 802.11b Wi-Fi like its predecessors, although the USB port was replaced with a proprietary connector. A compatible cable that connects to other devices' USB ports is included with the unit. The new multi-use connector allows video and sound output with the same connector using an optional composite or component AV cable. As with previous models, Sony also offers a cradle (PSP-N340) for charging, video out, and USB data transfer on the PSP Go. This model adds support for Bluetooth connectivity, which enables the playing of games using a Sixaxis or DualShock 3 controller. The use of the cradle with the controller allow players to use the PSP Go as a portable device and as a console, although the output is not upscaled. PlayStation 1 games can be played in full screen using the AV/component cable or the cradle.
The PSP Go lacks a UMD drive, and instead has 16 GB of internal flash memory, which can be extended by up to 32 GB with the use of a Memory Stick Micro (M2). Games must be downloaded from the PlayStation Store. The removal of the UMD drive effectively region-locks the unit because it must be linked to a single, region-locked PlayStation Network account. While the PSP Go can download games to itself, users can also download and transfer games to the device from a PlayStation 3 console, or the Windows-based software Media Go.
All downloadable PSP and PlayStation games available for older PSP models are compatible with the PSP Go. Sony confirmed that almost all UMD-based PSP games released after October 1, 2009, would be available to download and that most older UMD-only games would also be downloadable.
In February 2010, it was reported that Sony might re-launch the PSP Go due to the lack of consumer interest and poor sales. In June 2010, Sony began bundling the console with 10 free downloadable games; the same offer was made available in Australia in July. Three free games for the PSP Go were offered in America. In October that year, Sony announced it would reduce the price of the unit. On April 20, 2011, the manufacturer announced that the PSP Go would be discontinued outside of North America so it could concentrate on the PlayStation Vita.
