I think the M92's build quality is really good. It's not the toughest device I ever helt in my hands, (forget about what used to stand here: M92's exterior is entirely from plastic). I think it's in a pretty safe condition when carried around in it's case. The device's plastic parts don't jiggle around but feel tight and pretty resistant to moderate pressure.

It's just what you would expect from a device that's in the upper price class and doesn't bring any movable parts (contrary to e.g. a notebook that's always prone to cracks and defects caused by parts like the hinges, the fan, the hard disk, optical drive or even the keyboard).

I don't know the Pocketbook devices though. I have never touched one. But my impression from pictures and videos always was that the M92 is the tougher device. That too was a reason for my decision against the Pocketbook devices.
