Depends on what you're doing I suppose? I'm able to work on Zig with both of the devices I mentioned. Of course I'm limiting the test cases to the subset that's actually relevant to the area or target I'm working on. But that would be the case on a beefy full-size laptop too; even there, the full Zig test suite would take many hours and murder the battery in the process.

I've done all my dev work on devices much less powerful than this. After all, that's all that existed at the time :)
