My Laptop features a touch-screen, and I do use it on a regular basis - but only when I'm on the move.
As soon as I'm at a location where I can sit down properly, I switch to my mouse again.
It's fun to see people's reactions though, at least one elderly couple thought I was trying to break my laptop
As for the finger prints: true, especially when the screen is tilted in a certain way that reflects the light and makes them clearly visable. However, I don't feel the need to swipe my screen every time I want to watch a movie.
