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