Have had other similar discussions to this...
I've been opting for my MacBook Air M1 (13", 8GB memory) more for my work lately. I use DropBox mainly to keep access to files synced across computers.
Typically, I spent more time on my old 21" iMac (I think it's a 2015 model). Which is also where I have my external hd plugged in constantly for backups (not so with my laptop).
So I'm considering again making my laptop (or an upgraded model and size with perhaps more ports) the main driver, "retiring" the iMac, and just getting a better monitor to plug into when needed.
The current Mac Minis with all the port options was intriguing as well.
I'm wondering if others are using a laptop for the bulk of their daily work or need the sometimes higher powered desktop machine. (I will note that I've been happy with this Air for handling Glyphs files and some basic graphic work in Adobe apps even with the current specs.)
