Who wants a crappy mechanical spinny-plastic-disk interface taking up so much space and making clunk-noises in a piece of high-density techno-loveliness? Especially when it might get used once a month at most? Nobody. Apple have it spot on (again): If you need to get files off a CD, do it over a network, or use a USB stick. The retina MacBook isn't aimed at people who still want to drive around in a Ford Escort. Get with the programme.
