What is the tag for Macbook Pros with retina displays?
In this case, I created retina-display. Any better ideas?
Maybe the tag is too specific, or just untimely. Perhaps we should wait for a relevant non-hypothetical question before creating the tag, e.g. what problems Ubuntu is having on someone's Macbook that are related to the retina display -- specifically, the retina part?
In general, I think resolution is a good fit for now.
