I just picked up the midrange 13" configuration rMBP. It mostly looks lovely so far. However, when I press the "L" key, it usually clicks when I release it to come back up. Like a piece of the plastic gets caught on something. It always does it when I press the button hard, and sometimes when I press it softly. Anyone else getting this, or had it in the past? I got it at Best Buy, so I suppose I could take it back there. Any idea how long it would take Apple to fix it if I brought it to an Apple store?
