Hi- I have 2 macs each with their own iTunes libraries (different purchased music, etc). I'd like to put both of them onto my mini. However, when I tried to sync my mini with my PM I got a message (paraphrased here) that the mini was associated with another library, and only gave me the option of completely replacing the old library (the one on my PB) with the new one (on my PM). As I paid for all of these songs, it would only make sense that there is some way to get both libraries onto my mini, right? Any help would be appreciated. Thanks.
