Im about to buy the 12 inch ibook. Macworld says in their review that the superdrive is the only burner that iDVD or iMovie will burn to. Is this true? I seem to remember another post saying that the laCie external burner will work and that apple made a patch for it. What is the deal because it sounds like the 12 inch is the better machine if I add memory and I was going to buy external dvd down the road if needed.
