Spare a thought for open cockpit guys and flex wing pilots!
In the sun,rain ,cold !
Panasonic toughbook CF 18,
built in GPS ,wifi,hand jotting in flight, connect intercom to hear airspace alerts, moving skydemon,water proof,drop proof, touch screen with gloves,sun readable.
OK,it`s a lump 10" screen, but we use lap map boards anyway so, sat on my leg, works great.
At airfields, go online, update plan,live weather,notams ect,
