Because you can't fastforward the songs on the radio......so you store the songs locally and you have more freedom to listen to what you want....when you want. If you are thinking about this upgrade....you should start "ripping" you audio collection. See my phatbox thread in AW for some more background:caykroyd said:Since you can get 4gigs of mp3 on SD cards, what it the point of having phatnoise or ipod connection? I just drop in two SD cards with mp3s and have endless listening.
Am I missing something? Is it just the coolness factor?
