If you wait to buy a macbook which comes with leopard, yes you will need to buy a copy for the G5. I don't see why this is being "shafted". If you buy a macbook now, you could buy a family pack of Leopard (costs more, but allows for up to 5 installations). If you buy a new car, do you expect the old car to somehow be upgraded, or would you be shafted in this situation also?
