I tried running BlissOS on my Hi10 Air but that was a distrastrous experience. Slow, no touchscreen and above all, no way to get the image rotated correctly (I could only get a portrait-mode full-screen view).
And then I had the hunch to install ChromeOS on a fast thumb drive (Samsung Fit) following the instructions at GitHub - sebanc/brunch: Boot ChromeOS on x86_64 PC (supports most Intel CPU/GPU or AMD Ryzen / Sto, and that has changed my whole view of the entire Hi10. I now have a snappy enough device that still lacks touchscreen support, but the OS is intended for a keyboard + touchpad interface so that’s OK. Most everything else seems to work … and you get Android app support.
FWIW, I glued a Wavlink USB-C hub (a model with just 4 USB3 ports, plus a USB-C port for PD charge) to the back of the tablet so I can now even run it under charge. I did have to increase the USB-C male connector length of the hub a bit by filing off some of the connector housing, otherwise the charge feature doesn’t work on my Hi10. The included PSU is also to weak to charge the battery with the tablet on so it only increases battery lifetime, but in theory I should now be able to suspend the OS and recharge the battery.
