If they've revised the keyboard/trackpad in Mk IV then it could be a pretty solid little machine.
I also had some weirdness with the USB Type-C power adapter (ha I wish this was the only hardware I could say this about) but that may or may not have been fixed (in the Mk III) with a recent firmware update. Though it did take them the best part of the year since my vague and difficult to reproduce bug reports. A 12v barrel jack supply was rock solid. No surprise there.
I know it's no Framework, but it's nice to have a System76-a-like this side of the pond.
