As some others stated in the comments already, I am also interested in whether the keyboards on 2017 models are improved over the late 2016 model, i.e. do they still have those issues when the machine is warm?
QuoteOur MacBook Pro 15 (Late 2016) we use in the office also had some problem with the "S" key recently. The key stroke was either not triggered or triggered twice. However, the problem was gonge after a while.
This sounds very likely to be the said issue, quite common on 2016 models, and it only happens when the machine is heated up.
Also, gonge -> gone.
There is one person on reddit who had her/his 2016 MBP replaced four times with the same keyboard issue, and when she/he finally got the 2017 version, the issue hasn't appeared so far.
Could you also test this in your review please?
