As somebody who operates their computer mostly at docking stations, I'm not sure what the keyboard is going to provide when all other peripherals must be available. The promise of a laptop is that it works without additional trinkets. If I need a bag of accessories, I can throw in a foldable keyboard myself. And then I get to choose a nice model. There are split keyboards that are small to pack and very ergonomic for me.
A cool idea would be if it had an accompanying android/ios app that would turn your phone screen into a screen for this pocket computer. Then the foldable keyboard would make sense and you don't need to hunt for a monitor to be able to use it.
