I don't use my 2017 12" Core m3 with 16 GB / 256 GB much at all now. It's been 95% replaced by my iPad Pro 10.5" with Apple Smart Keyboard.
I guess the 16 GB RAM is wasted. I only truly benefitted from the 16 GB a few times on international trips when I didn't have access to my iMac, but otherwise for most of my usage, 8 GB would be sufficient. (Actually 8 GB was manageable, but having the 16 GB was helpful since I was running MS Word, Excel, and PowerPoint with a large several hundred MB presentations, email, PDF reading, and a ton of Safari tabs. The fact that PowerPoint had/has a memory leak made the extra memory even more helpful.)
But now, for most of what I do, my 4 GB iPad Pro is mostly OK. MS Office kinda sucks on the iPad Pro since there is no trackpad, but that new Magic Keyboard coming out in May for the 3rd and 4th gen iPad Pro should help lots. But it's moot for me though now since I've changed jobs and don't need MS Office much now anyway.
So, I consider my MacBook a tertiary machine, far behind my dual 27" screen iMac and my 10.5" iPad Pro. My next upgrade will be to a 6 GB iPad Pro with Magic Keyboard with trackpad. The MacBook will not get updated any time soon. Certainly not in the next several years. I won't be upgrading my iMac either for a good while. Assuming it doesn't break, its quad-core i5 performance with 24 GB RAM should last me at least until 2025.
