The result is not as good as I could imagine however it is perfect for its functionnality <3

• The goods :
  • Large screen : 10.3 inches
  • everything I wanted plus :
    • a full USB port which I can use to make my backup, to put some books, etc.
• The bads :
  • a bit thick (but as expected),
  • the battery lasts 6 hours (also expected),
  • the touchscreen was very glossy. I had to put a mate protection,
  • I must turn off the device with physical button because devices like radxa and other raspberry pi consume battery while halted (https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#typical-power-requirements)
  • the sdcard is not accessible (although it is possible te remove it and insert it. it's just it is very hard to have access).

I can share the software parts if someone needs it :)
