Hey guys, just a quick question that should be able to be resolved rather quickly. Is there any reason why the apple super drive wouldn't be compatible for both the air and retina mac book pro? I can just get one right and use it for both. The reason I ask is that my girlfriend just ordered a new air, while I ordered a new retina mac book. Don't really want to buy 2 super drives. Furthermore, are there any other (cheaper) options out there in terms of an external optical drive? Or is the Apple super drive the only compatible option? Before suggestions on 'googling it', I may be ignorant in terms of hardware, but I did try this avenue. No yields! Thanks guys.
