Got mine 3 days ago and am typing this reply with it.
Flashed rooted image immediately after I got the unit, and used magisk as root manager as recommended by Planet C.
Then flashed TWRP and Installed systemless xposed framework from there.
Later installed the force immersive module to get rid of the status bar and soft keys.
This device is smaller than I imagined in a good way and I learnt to touch type on the keyboard in 3 days.
This device is just amazing, so please be patient guys, it's well worth the wait.
Pretty remarkable gadget, isn't it.
As I was setting mine up -- an ongoing process, but I'm spending all my time in Linux -- I glanced over at my expensive and much larger ThinkPad that's just a few years old and realized the Gemini is much more of a computer than the ThinkPad is. (Though I would give a great deal for Gemini to have a TrackPoint mouse nubbins.) This thing is one cool little 'puter.
A must have gadget. Design wise even better than my nmb12 in some aspect, like the 2nd USBC port, decent amount of key travel, and the best part it's pocketable. It's one of a kind.
I know the android with gms is not FOSS but I've chose convenience over freedom. Hope someday I could be capable of making the leap.
