psp is capable of basic media functions mp3, video, wireless connectivity, good internet browser, Skype, and even has its own internet radio stations that dont play any real good music.
i have tried to log into my SIrius account to listen online, but i guess the psp browser cannot open it.
seeing as how SOny does not have its own music digital distribution service (that i know of) to compete with Itunes and Zune, perhaps SIrius can step up a deal with Sony for an easy to use app?
