PocketStation
The PocketStation was a miniature game console created by SCE as a peripheral for the original PlayStation. Released exclusively in Japan on December 23, 1999, it featured a monochrome LCD, a speaker, a real-time clock and infrared communication capability. It could also be used as a standard PlayStation memory card by connecting it to a PlayStation memory card slot. It was extremely popular in Japan and Sony originally had plans to release it in the United States but the plan was ultimately scrapped due to various manufacturing and supply-and-demand problems.
PlayStation Portable
The PlayStation Portable (PSP) was Sony's first handheld console to compete with Nintendo's DS console. The original model (PSP-1000) was released in December 2004 and March 2005, The console is the first to utilize a new proprietary optical storage medium known as Universal Media Disc (UMD), which can store both games and movies. It contains 32 MB of internal flash memory storage, expandable via Memory Stick PRO Duo cards. It has a similar control layout to the PS3 with its PlayStation logo button and its Triangle ('Triangle'), Circle ('Circle/O'), Cross ('Cross/X') and Square ('Square') buttons in their white-colored forms.PSP Go model
Released in October 2009, the PSP Go is the biggest redesign of the PlayStation Portable to date. 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, videos and other media.[87] 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, 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).[91] 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. The PSP Go is being produced and sold concurrently with its predecessor the PSP-3000 although it will not replace it. All games on the PSP Go must be purchased and downloaded from the PlayStation Store as the handheld is not compatible with the original PSP's physical media, the Universal Media Disc. The handheld also features connectivity with the PlayStation 3's controllers the Sixaxis and DualShock 3 via Bluetooth connection.
