The M1 is great, but I really dislike the limitation to 2 external displays unless you get the ultra model CPU. I've just gotten really used to my portrait landscape landscape setup! And of course I'm an outlier so corporate IT won't buy me an ultra CPU version. I guess that it's to force people to pay more, but it feels like such an arbitrary decision. Sure, restrict it to 2x6K displays, but I'm using 3x4K displays…
I know the thread is one day old but in case you read this comment... That's really weird though: on my 7700X the latest version of Emacs compiles in 1m36s (and 1m39s, only 3s more, when it's in "eco mode", thermally throttled at 85 C).
On the 3700X it was already only 2m25s.
I think there's something wrong if a M1 needs 5 minutes to compile Emacs where an AMD 7700X desktop only takes 1m36s.
