Gah, I dislike that. I even more dislike Apple's "late 2012" stuff. Please give me a specific name that refers to a specific hardware design. Things can get so confusing otherwise, especially when trying to buy something used. Yes, I know that there are specific model numbers... in tiny print... but if people don't know them or use them it is no help.
