From the article:
''The primary features of this service are voice and video chat. The problem however is that very few PSP users actually own the peripherals that allows this. Yes you also have the option of instant messaging but without the not yet released Qwerty keyboard this can be quite a tedious task. I personally like the idea of connecting to PSP users worldwide even if it's only to say "hello" but due to the lack of users owning the proper accessories this service is really losing its potential.''
