Are pilots texting and sleeping in cockpits?

We know pilots sometimes sleep in the cockpit but now they text message as well?

A pilot killed after crashing into Lake Wanaka was sending text messages as he flew the helicopter on its final journey. Friends of Morgan Saxton, 31, have confirmed the experienced Haast pilot sent texts to at least one friend from his newly rebuilt Robinson R22 helicopter, before it crashed on November 1. Another pilot says the practise is common - and claims it isn't dangerous as long as flyers aren't too distracted.
Toby Wallis said texting and flying was common among pilots and something he did himself.
"We might get a text telling us about another flight and so we might send a quick text back. It's no different to changing the radio station in a car, but it could be dangerous if you are distracted by it."
