Yes, again I agree.
However, it is possible to produce very good and very lgiht sun light readable screens. For example I have seen the Motion notepad in operation and while it is no where near as good as the G1000 or Avidyne screen it is a great deal better than other notepads and more than useable.
It is interesting on the PocketFms forum despite various suggestions no one seems to have yet found a reasonable portable screen for in cockpit use that is any larger than the car SatNav format (with the exception of one or two high end notepads like the Motion) - unless I have missed the posts.
I would have thought there would be a market for a slightly larger screen for in car sat navs. I have always thought the ideal format would be around A5. I reckon a light weight unit with pretty good battery life could be produced (in fact come to think of it around the same size as an iPad) but presumably no one feels there is a worth while market (and maybe they are correct).
