[*]Booting up and shutting down takes Bloody Ages™ (read: about three minutes), with absolutely zero feedback during the process, just a black screen, so you have no idea whether you pressed the button or WTF is going on.
[*]Closing the lid does not suspend the device and there is no setting to make it so.
[*]The screen scale factor can be set only to 100%, where everything is so tiny that you need a magnifying glass to read the menus and 200%, where most dialog boxes do not fit on the screen. Nothing in between.
[*]No sensible package manager, like Debian's Synaptic, only a very high level "Software". That is a major issue for me. I tried to find one but no luck. There is "Gnome Packages" in the repo that is utterly useless. Whatever I do, it just presents an empty window, despite having sources set correctly.
Having suffered the above, I was tempted to install Ubuntu on it. I found an "official" Ubuntu ISO (16.04.1-desktop-amd_0809_2) and tried it live. It shows up sideways which does not inspire confidence to actually install it.
