I'm hearing a lot of talk about the Retina display looking poorer than the non-retina (1440x900) displays when displaying non-retina content. Theoretically, shouldn't the Retina display (2880x1800) displaying 1440x900 content be the same, if not better (IPS) than a non-retina display (1440x900 native) since it's essentially just pixel doubling (4px = 1px)? What I'm looking for: -Opinions from people who have actually seen the two in person and can confirm any difference (or lack thereof) between the two when both are running at 1440x900 or when displaying 1440x900 content. -If the display is indeed worse on the Retina, then why it is (because it should theoretically be identical or superior - not inferior). EDIT: I had already considered the fact that the difference may be purely psychological (when comparing retina content to non-retina content) but I heard otherwise which is why I'm curious.
