Ends, I have used a crappy microUSB KB folio with my Nexus 7(flo) tablet, it is pretty damn crappy and no N900 clickyness; not sure there is a decent add on keyboard out there as I clack this out on my Cherry blues.
I cant love my damn tablet though because while I want the hardware to all work I have to learn a gob of new commands and tools to tweak it. I get by with best possible privacy with LineageOS microG fork to replace Gapps and services, but it is still, to channel Trotsky, a deformed Linux derivative.
No easy local/ssh cli experience knowing where all of the .conf files are and what standard tools will do what I want.
IDK maybe I am just getting old but I like real normal GNU-Linux preferably with a Debian base, I don't to work hard I want a nice garden with no walls like we dreamed for a Neo900 with a 1.0 quality OpenMaemo to run on it.
I would shoot for a similar experience that I have putting Ubuntu onto a modern gaming grade laptop, can I get a mobile device like that?
