The PSPgo features most of the same functionality as the older PSP models, with a few exceptions. The PSPgo lacks a UMD drive but has 16GB of built-in flash storage. The PSPgo also has blue-tooth connectivity allowing you to use a PS3 Wireless Controller to play games or connect to the Internet using Bluetooth Modems or via Mobile Phones.
The PSPgo also uses M2 Memory Stick storage instead of the Memory Stick Duo found in the older PSPs. The USB connection on the PSPgo is different to older models – it is used for both connecting to the PS3/PC and for charging the unit. A built-in microphone is included in so a special headset is not required.
