Hi! I think creating hardware is a wonderfully difficult process to get it right (and I have no experience besides building some hobby stuff). So first, I really like and admire the work behind the current state of the device and this is just to open some discussions about future possible improvements.
Here are my observations about the hardware:
It feels weird. If behind there are 4 individual buttons I would rather prefer 4 individual directional buttons.
There are small scratches around the sides
The slot is too wide and the micro sd does not gets flush when inserted
The slot is too wide (why the original design included the secondary micro USB?) and too near the pokitto’s leg (so, it is impossible to plug bulky ended cables)
5. Screen clamp
The mechanism for holding the screen looks flimsy and botched as a quick solution, in my two cases the little clip/clamp does not sit flush to the screen
6. Power switch
The switch cover can be a bit wider so the switch cover does not move diagonally. Also, I am not sure if OFF should go on top.
7. Back buttons
The rubber buttons do not fit properly. They are not flush to the case and do not look symmetric (centered inside the hole). And why there is no icons?
8. Embossed rectangle on the back
What is that?
