Even to this day there aren't really a ton of options for a non-devkit, non-router arm64 machine that you can use as a desktop workstation.

I was happy to see that x64 mini computers have really come along. Some of the units from China are really impressive with some exposed full PCI-E buses.

Arm64 is still limited for sure, but with Snapdragon and Windows finally committing to ARM I think the future is bright for that. Just not here yet.
