When I was commuting 2 hours a day on the bus, my daily driver was an 8-inch iPad that I used with a logitec keyboard case tethered to my iPhone for internet, and would connect to my VSCode on my $10/mo droplet using Code-Server.

If you offload the computer to the cloud, and don't need to do anything graphically intense, it makes daily driving an underpowered tablet very easy.
