Re: Pi-top
James,
On the subject of PiTop, I got one years ago for my grandson. My reaction was that for that purpose the location of connectors didn't work out very well. In particular the power and headphone connector were on the same side and as the power connector needed to be internal there was no easy way to connect plain old phones or speakers. Perhaps it would be worth thinking about how best to lay out the connectors for this sort of purpose - and then about something along the lines of chromebook except running NextCloud as the server (on a Pi, of course).
