We're traveling that day - I think we'll be on the road by 1p EST - maybe I'll just listen to the audio
My current machine (work and personal use) is an '18 Mac Mini (32GB/512/i7) and it has been pretty terrific, runs almost 24/7 and rarely has any issues. My main problem, was sketchy BT connectivity, I disabled the onboard BT and I'm using an external BT dongle (in a port on my KB), and that's been a complete fix now for well over a year.
I generally have dozens of apps open, several development tools, multiple browsers (gaggles of tabs

), communication apps, lots of local services (to support development), Containers, a VM, and it barely warms up. I run it without the bottom cover sitting on a large, multi-speed fan which definitely knocked off a few °C
That being said, as you know, the GPU performance is pretty weak, that's where the M1 based Mini just kills this machine. I use two displays, but I went with 25" QHDs knowing the '18 Mini was a little strained to drive two 27-30" 4K displays, so that would be part of my update, new larger, higher-res/better PPI displays.
I thought the initial Mini M1 product wasn't quite enough machine, I wanted a 32GB RAM option, a few more ports, and, I wasn't in a rush as I haven't quite sorted out the Winders™ based work I do. Some things I've migrated to cloud services (a couple of AWS RDS instances), other things, I could just fire one of my rack machines back up, maybe do a few component updates (they're both still running spinning drives). You know, just some general workflow type considerations in moving from Intel to AS.
I __might__ also switch back to a notebook. Before the Mini, I had only used MBPs, but I got to where I had no need for a "travel machine", and I kind of liked the idea that work takes place at my desk, and when I'm not there, I'm not working (vs. "
Hey, I can alway lug my work with me!")
I was still on a 2015 15" MBP before the Mini, it was a recall machine, I got the free battery (and top plate, trackpad) replacement, sold it for $750 after 4 solid years, traveling dozens of times between coasts, generating some, let's say, some decent cash flow

Heck, it was a freebie from a previous business partner (
"Can you make the trip a few times this month?", "I can, I need a new machine for the road", "OK, just ordered you a new MBP")
But recently, having a little portability has come up again, not for travel really, just for more freedom vs. being stuck at the desk.
We'll see, and a new Mini might not even be on deck, though I'd be surprised if the new generations of M1X/M2/M<something> machines didn't include an update to that machine as well.
Hahaha, sorry, that's a little rambly, not quite firing on all cylinders this morning.
