On this point I agree. When my 16" MBPs were undocked from an external monitor -- when it was just the laptop -- they were the coolest MBPs I'd ever used up until that point. Under light to normal loads, the fans were near-silent. I'll grant you that. (Plus they finally "fixed" the keyboard with the 16", but that's a separate story.)
The problem is that as soon as you connect them to a display, good freakin luck. You're on the airport tarmac from the very first minute. And, a large part of the time, I'm docked to a display.
To that latter point, some on here have said "Well then you should just have an iMac, or a Mac mini". This has made no sense to me. About 20% of the time I want to pick up my computer and go somewhere else. Why should I own a desktop?
Lastly, let me say this: I'm a huge Apple supporter. The company has its faults, but they are a BigCo I'm happy to root for. This issue on the 16" was a major mess-up on their part. Now they birthed the M1, and all is right in the world. But I'll never forget the mud they dragged us through with this 16" fiasco.
