Hello...I saw them doing this at the Apple retail store at the genius bar, they were usig their Ipod to transfer a program (that I needed to add to my Imac that I did not have ie: Iphoto) to my Imac. That being said I want to use my Ipod shuffle to move files from my Imac to my Power Book...I have been reading the threads here and found I can transfer my Itunes music by using a ripping software (thanks for that info)...but how do I transfer reg files...I tried to open a doc. and 'save as' and locate my attatched iPod but coulnd not figure this out...thanks for all the advice!
