Work for a university. We have a number of students in Africa, southeast Asia, and eastern Europe taking online courses. We do not support Windows XP or Vista, except for in the case of these students. Some of these guys don't have the resources for anything else.

I also know that we get a number of students connecting with Android v3 or earlier from these same locales.

Something like Ubuntu sounds like a great fit then.

Modern ubuntu is getting pretty heavyweight. Gone are the days it'll run on any old laptop.

Absolutely. I just refurbished old Core 2 Duo desktops. Ubuntu creaked along (it was Disco Beta).

I found Linux Lite, based on Ubuntu 18.04 LTS:
