I recently bought a Retina Mac Book Pro and all of my iTunes movies look kind of sad on it. I was going to get a Super Drive, but is there a blu-ray version of it? I want to be able to burn DVDs but also play blu-rays... don't need to burn blu-ray though. I don't know if anything like this exists. If there isn't something that does both, is there anything that can at least play blu-ray? Thanks.
