I am a newish MacBook Pro user and helping a friend purchase a MB Pro or Air. The functions he wants are dated, but important to him. He wants to be able to play and burn music cds, watch movies and edit music. He has minimal needs (emailing, googling, photo storage, word processing). Can both the Pro and Air do this? With an external drive, I'm assuming. Would that be the Apple USB Superdrive? Please advise.
