I hate when people do this. And I'm surprised by how many people don't understand the problem.
It's not necessary to touch the screen even if you're pointing something. Grab the mouse (or use the touchpad) or just point without touching. Is it so difficult?
It's obviously a habit acquired by interacting with paper and less fragile (and expensive) media. But for me it is a sign of ignorance.
I hate this so much that I avoid to bring my laptop at meetings unless it is strictly necessary.

Point without touching please. I never want to touch someone else's mouse or keyboard. They are among the dirtiest most germ infected places you can find and touching them is bad for both you and the person with the keyboard / mouse / touchpad.
