Likely not the reply you were looking for, but in theory a PineNote would be a great "donor" device for modification. For example - get your favorite SBC (Raspberry 5?), figure out how to connect it (likely eDP, documentation shouldn't be hard), make a new shell/body and you're done!

...If you have the technical know-how, time, space, tools and motivation of course.

It's not that no one does such stuff (see r/cyberdeck), but yeah admittedly if you're not an engineer it likely isn't the easiest.
