I'm getting closer to needing a DVD burner. I've always thought that I'd be waiting until I could justify the expense of a Mac w/ a Superdrive, but now I'm thinking I might be better off getting an external DVD burner, sooner than later. I know that Apple's iDVD needs an internal drive, but I'd like to hear opinions about how much I'd be losing by getting an external sooner than waiting for when I can justify the cost of a new Mac. Thanks, Carl
