I’m soooo close to going ahead and selling my MBP. I haven’t used it once in the month since I got the 12.9, and I have a hard time imagining needing to. And I’m thinking if it turns out I’m wrong, I can get a Mac mini and still have come out ahead.
This is exactly what I did. Once I got my iPad Pro I decided to pair it with a Mac mini and gave my old MacBook Pro to a family member. Now, I almost consider the mini to be a peripheral to the iPad - i use to pretty infrequently, but when I do I use it for the rare things that I need macOS for, plus backing up my iOS devices. It’s also very nice to have an always-on Mac in the house. I use it too as a server for files and for Homebridge, which didn’t work with the laptop.
The mini doesn’t even have a monitor anymore and I just use the Screens app on my iPad to connect to it. It works perfectly for my needs. Being able to use a mouse and trackpad would make everything so much nicer, so hopefully someday. I still have access to the MBP but I’ve used it maybe twice in the year since I made the switch.
The mini + iPad Pro is a really nice combination for people who are thinking of using an iPad Pro as their main device. It made the switch a lot easier for me.
