Clamshell Tablet, HW KB, 5.5", Cherry Trail AMD64
 

I found the Cherry Trail X7-Z8750 GPD Win 5.5" GamePad Tablet PC while poking around auction and geek sites.
I have Ubuntu running on a Atom AMD64 Cherry Trail thin client for my kids but the driver building is not so simple. Binary blobs requiring backporting the kernel and holding back normal upgrades, though I see there are custom made builds of Ubuntu that is supposed to support the bluetooth 4.0, WiFi, and sound. I worry about driver support in real GNU Linux for the hall and inertial sensors, touchscreen, as well as the gamepad buttons.
A fully GNU Linux supported clamshell/tablet like this, preferably with FOSS drivers, paired with a candybar phone that has a good battery life and obviously bluetooth tethering.

Has someone overslept? ;)
