Hello, folks; I have an iBook with these specs iBook G4, 1.2 GHz, 512 L2 Cache, 1.25 GB memory, 60 GB harddrive. and am going to be giving this to a friend's 14 year old so he can use it mainly for GarareBand. Has anyone used GB much on an iBook like this one? How will it work? Are there any performance issues to expect, or quirks? I ask so I'll be prepared to help out if need be. Thanks, Mark
