I do like apple loops and have several jam packs. What bothers me is that with Logic pro you get everything in the jam packs, but apple doesn't tell you this, so now I have bought them twice when once would do. Several of the jingles, loops and foleys have been used to death in commercials on TV and radio and you will recognize them instantly, so you have to fold spindle and mutilate them into something new otherwise people will instantly know you did your song on a mac in Garage Band or Logic. There are also some places that openly sell you boots of these jam packs, so watch out.
