As there does not seem to be a thread for this new device, an HDMI Google OS stick with Armv7h Rockship 3288, I start it here with my own experience installing Arch Linux ARM on it
Short conclusion -
I managed to install it with LXDE and Plasma Desktops.
Plasma is very slow with lots of video artifacts.
LXDE Desktop runs very smooth.
Caveat: Chromium latest version is broken, but there is a special compiled version by geek for RPi2 v.47 which works.
No video acceleration, so probably no video playback or games, though not checked.
