If I were to buy another laptop, it would preferably be in the 12-ish inch size range and fanless. I could consider up to at most 13-ish if the bezel sizes were decreased, but the 14" is just too big for my tastes.
However, my current 16 GB 2017 12" MacBook is still fine for my usage, and my next purchase would likely be an OLED iPad Air / iPad Pro at around 11" or so, probably with Magic Keyboard. My current 10.5" iPad Pro is fine, but I would prefer OLED and slightly bigger screen, with a slightly wider aspect ratio, along with USB-C and a second charging port (in the Magic Keyboard). Face ID would also be preferred, or at least Watch unlock (which currently is not supported).
Right now when I go on short trips with no need for macOS, I just take my iPad Pro. When I went on longer business trips (pre-Covid), I'd often take both my MacBook and my iPad Pro (or iPad).
My main beef with the 12" MacBook is not the screen size. In fact I think it's screen size is very nice. My main beefs are the keyboard and trackpad, and the lack of separate charging port. The 2015 keyboard sucks, and the 2017 keyboard is merely OK. As for the trackpad, its feel is just not so robust. he click feel is better on the MacBook Pros of the same era. Also, I would have rather had a separate charging port than the headphone jack. Courage!
14" and 16" MacBook Pros are coming soon most likely. Furthermore, I'm pretty sure that Apple can do more than a few things at a time.
