PSP memory was key factor for Skype decision

Following on for its official announcement of support for Skype wireless communication on PSP, Sony has confirmed the reason the service will only be available on PSP Slim & Lite (PSP-2000) is due to memory differences between it and the original PSP (PSP-1000).

Nick Sharples, director of corporate communications, Sony Computer Entertainment Europe, told us:

"Although PSP-1000 and PSP-2000 are identical in basic functions, there are differences in hardware specifications to some extent and for that reason, PSP-2000 may differ in features from PSP-1000. We had studied the possibility of supporting Skype with PSP-1000 but had to give it up because of the smaller size of main memory on PSP-1000 series."

PSP Slim & Lite features 64MB of internal memory, while the original PSP only has 32MB, making it slower when loading games and, crucially in terms of Skype, web operations.
