I have the 13" from mid 2014. After only about a year, one of the cursor keys developed a split, then broke. Now I have an area on the left side of the keyboard causing various keys to fail occasionally — the '2' in particular, the 'a' now also. These issues are insignificant compared to the problems I've had with the screen coating; my first Mac laptop has been a pretty disappointing experience overall.
