As continuation of my initial comment: (too bad I haven't saved the pictures)
After sleep I had some thoughts on design:
first I thought on repairability:
Maybe you should make back easy to remove?
My thoughts were to have 4 screws under kickstand + latches (or however they named) on perimeter. Convenience of disassemblement is really important if you dropped the tablet in water (also easy to detach battery). (Water resistance usually damages the quality of speakers (I like the way how it's done on samsung s7, but I heard a lot of complaints about it's sound))
Second thoughts was about touchpad gestures:
I really love two-finger scroll, together with scroll inertion. If it is possible to be done without breaking scrolling in games and background windows, please do it.
I like drag-lock, it's really convinient, though maybe it's useless with touchscreen, also I would like to have right-button drag, never had touchpad without physical buttons. Some way to have middle-click would be nice as well, also Cortana gesture, not sure if I need gestures to minimize/maximize/restore the windows and to switch virtual desktops
