Following the news of impending Skype support
on Slim PSPs, some were left wondering why the plumper PlayStation Portable failed to answer the voice over IP call. Speaking to SCEE's director of corporate communications Nick Sharples, Pocket Gamer
has ascertained the simple answer. It has nothing to do with looks, and everything to do with the older PSP's waning memory and inability to remember long strings of numbers (just like grandpa).
"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," said Sharples. If you recall, the PSP-2000
benefits from 64MB of internal memory (as opposed to 32MB in the older model) which is used for UMD caching and the reduction of game loading times. The same enhancement also enables Skype to run and thus excludes the original PSP from online chatting. We certainly hope early adopters don't get too hung up on the disappointment [Goodbye! - Ed]
