I have an answer. I work out in LA, but I have several close friends working with the board of Ed. in NYC. MacBooks are given to faculty on loan. They don't get to keep them! Recently my friend got kicked upstairs and is in charge of buying MacBooks. Most have been the new Touch Bar models. A few were Airs. Most significantly there have been thousands purchased. According to her, she's had zero returns. Not one came back as defective. No clicking keys or uneven screens or trackpad issues. That's a pretty good sign of good quality control. Now here in LA I work with clients who are editing movies, writing screenplays, still shooters (like myself) and many of us have the new machines. I have yet to hear of a single problem from anyone. What this proves, at least to me, is this: 1) Forums like this will attract people with genuine issues. This will give the appearance that problems are more common than they truly are. 2) Forums like this will also attract non-owners and folks with an agenda. This makes #1 appear even worse. 3) MacBooks are pretty darn reliable. R.
