hello, i am considering buying my first ibook G4 but first wanted to know if anyone knows about the garage band software that comes with it. i would like to use gb to record my music lessons which go for about one hour each and eventually store them all as mp3 files on my machine. is it possible to do this with garage band and does anyone know how? more info on gb would also be really appreciated. alternatively, is it possible to digitally convert audio cassettes to mp3s on the ibook G4? thanks in advance!
