I got myself a 16/512 M1 mac mini in the office to try it out. It's a very nice machine, but it's stuck to the desk so I can't take it to a meeting room to do an online meeting. Since several people got a new M1 MBA in the meantime, I'm repurposing a 2012 12" macbook for that. Not ideal, but it'll work.
Now at home, I'm also reconsidering my options. I'm looking to set up a home office and a mac mini is one of the options. But there also, it's the lack of portability. I also have a music setup with a keyboard, audio interface and as those things go, it's likely to be expanded with more USB stuff later on. If I build this music setup on a desk on one wall, then I can't move to the other desk when I'm working for my day job. So I'm considering the new rumoured Apple Silicon 14"/16" machines with a docking monitor on both desks. I'm currently using a 16" in that way (minus the docking monitor for my music setup, but with a monitor for the day job) and it's a little bit of a hassle to lug it around and reconnect it. But at least it's just one machine to manage.
It could be suggested that moving and replugging a MacBook from one desktop to another is just about the same as moving a Mini - unless you want to use the MacBook’s display simultaneously with the monitor…..
