I have a PC and a Touch, with all my content on the PC (music, apps, movies). I'm thinking of buying a Mac Mini to start some development. 1. Someone told me that if I connect the Touch to the Mac for development then all my content must come from there too, because iTunes only syncs content with one machine. Is that true? 2. Is the Mac Mini powerful enough for simulating 3D Touch apps? Any issues there? TIA.
