If I had to replace my old Chromebook, I'd probably go with this:
https://www.amazon.com/Chromebook-2560x1600-i5-1240P-LPDDR4X...
Decent CPU, 16gb RAM, 256gb SSD, quality screen with a thin bezel.
I like the extra memory because I sometimes run multiple Linux containers at the same time.
If you only want a dumb terminal for web and SSH you could easily get by with half that without sacrificing performance.
