Thank y'all! I'll have to look into that
4-port Gomadic thingamajic, which I could use for my reader, phone and Nintendo DS.
The numerous different Sony reader tips confuse me though. Are they really any different, because while PRS-700, 500 and 505 are available, there seems to be no dedicated PRS-300 one.
I'm gonna have to wait for my next paycheck anyway, I'll have to ponder the Gomadic/PSP choice for the time being.
