I've made myself a split wireless keyboard in part so that it can be more portable than having the style of keyboard in the article in my bag. And that's replacing an Atreus, so already relatively compact.
But then, there are degrees of portability. This sort of thing is fine for a coffee shop. Better, in some ways, than a laptop because it's usable in full sunlight.
It's only the fact that everything's wireless that makes it practical, really. I'd be tempted to print up a chassis for the NUC and the power bank so that they become a single unit, then the only setup is the glasses cable.
