IMHO the Motion 1600 is too big (width x length) for cockpit use.
The LS800 looks a lot better, and it does display the two essential portions of the Jeppview plate adequately. JV plates were (apparently) designed to work on 800x600. A lot of pilots still use the old Fujitsu LTP600 tablet; they come up cheap on Ebay.
There isn't a perfect solution on the market; an LS800 with a 1024x768 LCD and half as thick would come close though.
There are "certified" display devices for airliner/bizjet cockpit use. You get two of them; they are just thin lightweight LCD panels connected with a cable to a remote computer box installed in the aircraft, and the only control seems to be a brightness knob. One has dual redundant power supplies, etc. I don't have the URL handy; it's an American product. Very expensive.
