If I was flying a Cat III ILS at night, into Zurich, with a 'glass cockpit' I might give this some thought, but I don't think your average, GA, recreational pilot has anything to worry about, enjoy the technology that allows you to call your girl-friend to be waiting for you as you land.
But if a student, don't start texting her before you've raised the flaps after landing - as one of mine did ! If I hadn't thought that I might damage some part of the airframe, I'd have hurled it, and him, out of the cockpit !
Damned phones, what was wrong with Morse Code ?
