Play along - create a PinePhone keyboard

[Michael Arthur Long]

I'd like to remind everyone that the BlackBerries had a teeny tiny trackball(or an optical trackpad later on).
You could still get them as modules for Arduinos, so it seems to be an option if anybody wants to incorporate them into their keyboard designs.

Or even just have them in the back cover without a keyboard and figure out the use case for it later. idk.
Also, the PS Vita had a whole trackpad in the back.
