Of course a laptop with case, screen, battery etc costs more than a bare SBC.

The Milk-V Mars, with very similar performance to this (see other comments for JH7110 vs TH1520), starts from $39 with 2 GB RAM (and 4 GB or 8 GB options) and of course quad core 1.5 GHz dual-issue CPU. That's around 8x the compute performance of the 1 GB MangoPi MQ-pro, for $10 more. Or, for more bare-bones, the Mars CM is $34.

Thanks for the suggestion. I'll admit I was really disappointed with the MangoPi.

I still think I'm going to wait a few years before buying another device.
