This is a cool - and odd - device. I’ve been eyeing the uConsole for a while, but haven’t made the plunge since its still in pre-order, and the actual device you got is build on Risc-V. This isn’t a widely adopted architecture, so you are in for an adventure.
Would love to hear what you think of the device. And if you get tired of it, PM me as I might be intrested (at the behest of my partner).
If you don’t mind clutter free, simple presentations, try hack.md or cryptpad. Both supports markdown styled presentations, both are FOSS cloud applications and the format of the presentation is highly portable.
If you want to get really ambitious, try marp framework for presentations - still markdown but on steroids.
