The PSP Go is a version of the PlayStation Portable handheld video game console manufactured by Sony. 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 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). 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 new features make the PSPGO what is said to be, a new proprietary multi-use connector is used for USB connectivity. A suitable USB cable is included with the unit. The new multi-use connector allows for charging and USB similar to previous units, but also allows video and sound output with the same connector (with optional Composite AV cable and Component AV cable), unlike previous offerings which had TV OUT functionality on a separate port to the USB port. Sony also offers an optional cradle for charging and USB data transfer on the PSP Go, similar to previous offerings.
The PSP Go adds support for Bluetooth connectivity, enabling the use of compatible Bluetooth headsets and tethering with Bluetooth-enabled mobile phones. This also enables users to connect and play games using a Sixaxis or Dual Shock 3 PlayStation 3 controller or Bluetooth Headset. Internet Skype calls can now be made using compatible headsets; and more importantly, a change to the control scheme. The PSP Go features convenient slide out controls. Although these are consistent with historical PSP controls--featuring four directional arrows, the four familiar Sony face buttons and a left-oriented analog thumb stick--their ability to be placed out of view when not in use allows the PSP Go to maximize the use of its screen and your viewing pleasure.
