I think at this point the niche would be well-served if one could have a competent clamp-on landscape keyboard (so close, clicks keyboard) for their phone they could use to RDP into a better machine that could run while the phone is off. Additionally nice would be if the phone had a fully functional usb-c port that could do DP and usb for docking. At that point I'd have serious thoughts about retiring my backpack or nanote next. It frustrates me how close we are, if such a keyboard existed for $80 or so
