Great points! I agree in most.
Point 1, I think the braided cable may help compensate the fraying but it's a valid point.
Point 3, that has been happening since 2016 machines. We've experienced it with every generation since then, forums are plagued with these kind of complaints, after so much time I'd think they haven't found a fix, though it's entirely possible they are ignoring it altogether since they sell anyways. Audio management is pretty chaotic OS-wide when having several audio sources. This is more of a nitpick, but the sound enhancer should be toggled real time as you play music not after 3-4 seconds.. feels amateurish.
Point 5, yea no kidding! dongles aren't as reliable as connecting to the port directly. One thing we like from Apple chip vs Intel, no more screen flickering when plugging in an external monitor. Also you can play 4k vids without the laptop taking off.
Point 6, completely agree! Actually the keyboard is nice, but feels a bit flimsier than previous non-butterfly keyboard generations. Also it's backlit angle bleed is a step back as well.
All in all, something I'd like to give hands down to Apple for, after months of use, I literally haven't heard the fans spin, even slightly.
