For the last 25 years it's been taboo to touch my computer screen and heaven forbid touch a co-workers computer screen. It was as evil as pressing your lips against the kitchen glass sliding door. Now, everyone wants to touch the screen. Tablets and ipads are great for consumption - watching movies, playing games, and menial tasks such as social posts etc but they should never be a serious tool for production of anything from code, to media, or content and the reason.. Leachpad is really the best descriptive term. Lastly, you have finger prints all over your screen which is the reason, for the last 25 years, the rule has been "DONT TOUCH THE SCREEN!"
