A friend of mine gave his old iBook back to Apple and bought a Rev C PowerBook 12" last year, and only paid the difference of what they gave him for the iBook (the difference was about $600). I have my Rev D PowerBook 12" (I got it in February), and if they update the PowerBooks next week, I may want to "trade-in," like my friend did, for a newer 12" (crossing my fingers 
) or maybe even a 15". Does anyone know exactly how this "trade-in" thing works, and how do I go about doing it?
