Ah, yeah. My normal keyboard is the HHKB and the Fn key mappings match most of the HHKB’s. The trackball didn’t bother me too much, worked fine more or less, but I use ratpoison instead of a DE (not a very mousey UI) and most of the coding I do is either acme (somewhat mousey editor) or vi. I did stutter some when writing SQL or chatting with people, but for the most part, I’m close enough to regular typing speed on it that I can stop noticing the keyboard.
I have some WiFi troubles on mine, so I’m using a USB WiFi dongle until I get around to fixing it.
Assuming it’s not all due to the complicated setup, there was a thread somewhere around here about the CM4 defaulting to using the onboard antenna and ignoring the one that is actually plugged into the board, which makes a bigger difference on the metal-bodied uConsole. Apparently, that can be toggled with a kernel parameter: sudo sh -c 'echo "dtparam=ant2" >> /boot/config.txt'. (There was some elaboration in the thread but I don’t remember which thread.)
