Far more worrying to me is the butterfly keyboard in this scenario (for dev). The Ctrl, Tab, Return, and especially the A, J, K, D, and T keys get a lot of use and currently aren't tough enough to withstand constant usage. I've already had to replace the butterfly switch under the J key because one of the tiny clips that hold the switch in place in the corners snapped off. Fortunately I was able to blow the broken off piece out and prevent the key from going catatonic until I could replace it, but my left Shift key got a tiny speck of something underneath of it and is now refusing to register `:` half the time, which is incredibly frustrating for a heavy Vim user.
The non-user-replaceable battery is another annoyance. We all know that heat is the enemy of Li-ion batteries. I'm working remote in SE Asia, and even with office A/C it's very hot here. This laptop is a little over a year old, has never been used outdoors or outside an office, and it's already in "Service Battery" mode and shutting down at around 70% charge. This is completely unacceptable. I'm going to have to take it to the Genius Bar and be without my work rig for about 2 weeks if I'm lucky, and it goes without saying that I have a lot of user-centric settings and config enabled that would take me hours to replicate on a borrowed rig (even though I can clone my dotfiles and part of the config).
As Marco says in the article, developers are the biggest cohort of Apple's "pro" users. Apple needs to go back to the drawing board and make a truly pro keyboard that can withstand the rigours of touch typing and massive amounts of key entry, and can resist a very modest amount of dust.
Something sounds very wrong there. Unless you are regularly using it in areas above 35° C it shouldn't really matter.
