I noticed there's a bit of correlation with how hot the machine is running. Ironically, I bought this upgrade to my previous MBP (another 13" from 2013) to run docker better -- but for anyone who runs docker for development knows, the machine runs hot.
The keyboard isn't so bad once you get used to it (I type fairly fast at 120-150 wpm), but the keyboard reliability issue is really something that bugs me as it affects productivity. If you're a programmer, needing to train to use the shift key on the contralateral side is a pain -- especially give all the muscle memory that's been trained over the years.
