[edit] Distinguishing featuresUnlike its competitors, which largely use face buttons on their controllers denoted by letters (generally A, B, C, X, Y, Z), PlayStation controllers uses shapes; namely The Select button is a raised rectangular button while Start is a raised right-pointing triangle. It was the first controller design to feature 4 buttons on the top [L1, L2, R1, R2] (named by the side [L=Left, R=Right] and 1 or 2 [top or bottom] and commonly referred to as shoulder buttons). Beginning with the DualShock, the left and right analog sticks could also be depressed as buttons. These buttons are referred to as L3 and R3, respectively. Beginning with the PlayStation 3, a 'PlayStation button' (featuring the incorporated PS logo and similar in function to the Xbox 360 "X" logo button, but the PSP had the "home" feature before the Xbox but was later changed to the PlayStation button with the PSP 3000 as seen on the PS3 controller, and at E3 2005, the PS3 was shown with the "home" button) was added to the controller, in place of the 'Analog' button. The Analog button activated the analog sticks on the PlayStation and PlayStation 2 Dual Analog, DualShock and DualShock 2 controllers. On the PlayStation 3 Sixaxis and DualShock 3 controllers they are either both in use and have different purposes. The PS button on the PS3 brings up the PlayStation 3 home screen (similar to a PC "desktop" screen) while holding it down brings up system options (such as quit the game, change controller settings, turn off the system, and turn off the controller).

By March 31, 2005, the PlayStation and PSone had shipped a combined total of 102.49 million units,[1] becoming the first video game console to reach the 100 million mark.[2] [edit] PlayStation 2 Main article: PlayStation 2 Released in 2000, 15 months after the Dreamcast and a year before its other competitors, the Xbox and the Nintendo GameCube, the PlayStation 2 is part of the sixth generation of video game consoles, and is backwards-compatible with most, if not all, original PlayStation games. It has also been released as a media center configuration and also, like its predecessor, a slimmer redesign. It is the most successful console in the world,[3][4] having reached over 140 million units in sales as of July 20, 2008.[5] On November 29, 2005, the PS2 became the fastest game console to reach 100 million units shipped, accomplishing the feat within 5 years and 9 months from its launch. This achievement occurred faster than its predecessor, the PlayStation, which took "9 years and 6 months since launch" to reach the same benchmark.[2] It is the most popular console in the series.

Instead of the UMD drive as found on previous models, the PSP Go has 16 GB of internal flash memory and Memory Stick Micro port that accepts cards up to 16 GB as opposed to Memory Stick Duo. Currently the PSP Go has a max memory of 32 GB but the M2 memory can be increased in firmware updates. Games must be downloaded from PlayStation Store. The sliding mechanism on the screen hides the main face buttons and the analogue nub when not in use.

As of 2009, 50 million PSP units have been sold. The next and co-current revision of the PSP, the PSP-3000 released in October 2008, added some additional features, including a microphone for use in Skype, as well as an updated screen.[20] The other co-current revision is the PSPgo released in October 2009. The PSPgo is redesigned now featuring a sliding screen which sliding the screen up reveals its buttons. It also does not support UMDs, but instead uses 16GB of internal flash, as well as Memory Stick Micro, for digital distribution of games and other media. This redesign, however, is not to replace the co-current PSP-3000 model.
