Agreed, hands on before parting with cash! The resolution might not be up to much but I do like the idea of the head tracking. Probably wouldn't work with Orbiter without coding an interface but I could imagine glueing a couple of LEDs on the top to use it with TrackIR.
This scares me as well:
60 Hz progressive scan display update rates
I have used similar devices back in the days of Duke Nukem 3D.
It's an LCD, so unlikely to be a problem; they don't have the same flicker as a CRT.
