Unique to the PSP system is its connectivity. Multiplayer gaming, accessing the PlayStation Network and downloading apps like Skype are all possible. Once connected, users can browse the Internet, connect to a PlayStation 3 or even remotely access other devices like a PC, DVR or TV.
Models
Different PSP models are available on the market. The basic models are the PSP go system and the PSP-3000 system. Although the basic features are the same, the PSP go system is much smaller than the standard-sized system. Sony also sells several PSP system bundles that include a game.
