I was really interested in that and so very nearly backed it but was wary of the software support. Can you elaborate on the Debian issues? Would you still recommend one? (I don't care about telephone features)
+ settings for screen-lock-on-idle aren't saved - sometimes I want the screen to be always on, but it doesn't work
+ screen brightness goes to 100% every time you unlock the screen (and to lower it again, you have to increase it first)
+ and a few other things in that ballpark
Maybe they fixed it, but a while ago the whole update process broke because of a bad Open Office package.
I'll switch to Android / Kali Linux (which wasn't supported in the beginning) soon.
EDIT: But yea, I would still recommend it if you want something super portable with an actual keyboard.
I don't know if I would pay the retail price, though.
