I personally prefer writing on paper. I do an English degree, so I know that if I were to not write in a single lecture for 11 weeks, I know when it comes to revision or even the exam, trying to write again will fall outside my nature and I bet my hand would hurt so much during the exam, and there's nothing worse than a sore hand during an exam cause it slows you down like you wouldn't believe!
I also find people tapping away very annoying and distracting, esp when the lecturer's microphone has broken. I also find it very annoying when people change tabs/swipe across cause human eyes are naturally drawn to things that move. So when that happens, I start to lose focus! And before you know it, I'm trying to look at someone's facebook page and then all of the sudden, I've missed about 5 slides!
