And which stack.

Unless I am doing something very wrong (and sometimes I do), most of my Python development flows fit very comfortably on a 4GB Celeron laptop (that's currently with my 8yo daughter).

If they can't perform decently on this, I need to fix it.

4GB is a lot of memory. A lot.

The ones that matter. United States, Canada, UK, Sweden, Japan, Australia, etc.

I live in Ireland and I really enjoy that small Celeron I mentioned in the other message - the one my daughter is using. It's small, the battery lasts for at least 5 hours, completely silent, and, while it certainly isn't as fast as my Mac or the Dell (or the Xeon under my desk), it's fast enough for my tests to run while I think about the next steps. And it did cost me about $200. It's an expendable computer.

I assume a Pinebook Pro is a much nicer experience.

By your own admission, you own 3 high-end laptops and one low-end one (which you don't even use). Enough said.

They won't matter for long if they only target internal markets.
