According to Boing Boing one big design shift with the F-35 is that it removes many of the small physical switches that crowded older jet cockpits, and replaces them with a big touchscreen.

However, pilots are reporting that the touchscreen causes some serious problems and there is a 20 percent error rate.  The pilot said that while the cockpit is beautiful to look at it is not beautiful to interact with.

"The drawback is in the complete lack of tactile response. It can be challenging to press the correct 'button' on the display whenever the jet is in motion as it is quite a bumpy ride at times. At present I am pressing the wrong part of the screen about 20% of the time in flight due to either mis-identification, or more commonly by my finger getting jostled around in turbulence or under G. One of the biggest drawbacks is that you can't brace your hand against anything whilst typing – think how much easier it is to type on a smartphone with your thumbs versus trying to stab at a virtual keyboard on a large tablet with just your index finger", a pilot said.

While the biggest advocate of the touchscreen, Apple is scrapping the touchbar this year, pilots are stuck with that F-35 touchscreen for as long as those warbirds are in the air.
