RE:  Below John says that airline and military pilots use touch sreens, and he is right.This is incorrect.

In my 45 years of military and airline aircraft engineering experience, I have not seen touch screens utilized to any significant extent in military or commercial aircraft displays.  They have all used "programable hardware keys".  Look carefully at their displays you will see a row of hardware keys on the bezel that surrounds the display. The use of these programable hardware keys gives the best of the touch screen world where you can change the key function based on the displayed options, without sacraficing the ergonomic advantages of a real key.  The labels and functions of the keys change, but you press the hardware keys

It is really more than simply tactile feedback.  The ability to rest a gloved finger on the key before pressing is essential in the g-loaded world of flight.  Note that in many cases the keys have short guards, or more correctly, guides between the keys to help prevent dual or incorrect key presses.
