You could even have a look at the
NavAero website and consider the T.Pad
It's a remote screen for laptops, laptop gets stowed away (anywhere) in the aircraft and the T.Pad straps to your knee with Velcro strap - just like any kneeboard.
The screen is 100% daylight readable and will show whatever you can see on your laptop - aboslutely anything - all pages of all programs - from Solitaire to moving map, GPS driven, flight software.
In the evnt of a lighting failure, select an empty white screen on your T.Pad and you'lll have plenty of light to see the flight panel.
It's actually quite a neat bit of kit - and the kids can watch DVD's in the car on the way home.
