Thanks a lot.
I am still torn between the 2 flavours… The 2 screens & many buttons versus the compact design 
A very good starting point where the OS any other software-specific items could be added.
This may be a good further addition to others:
Is there a specific reason why the Duo X & the Dwarf do not use USB-C as a charging adapter?
USB-C can provide the required power.
It would be good to avoid e-waste & carry less stuff
