I do use Raspberry Pi 400 for accessing other machines via SSH and browser. Lack of memory really limits being able to replace a lot of desktop workflows, so I still do most of my work on a i7 powered LG Gram 17 that runs Kubuntu. The Pi is significantly slower than four year old i5 MBP and way slower than the i7 for building node apps and compiling Go... but, it's fast enough it could be usable. I do love the keyboard form factor. It is a pretty impressive device for the price, and has this old-school "home computer" vibe to it.
