I did - I believed all the '8 gig is fine' stuff at the beginning, and didn't like how much Apple charged for RAM. But for my work anyway it often starts having stuttering and slowness issues if I have too many things open. Otherwise it's quite fast.
I have the 16 gig version since 2020. Overall its the best machine I have ever owned but even then, maybe in 10% of the cases when too many chrome tabs are opened, VSCode and a bunch of other apps are in, I can sometimes notice the slow down but its not super critical.
I did have severe issues with Kernel Panics, the laptop would just blink a pink pixelated screen and restart but that has been fixed.
I'm tempted.
I also think 3nm is going to beset with production problems, I don't think it's coming around anytime near.
