Laptops and desktops can have touchscreens too. When having a small viewport less stuff fits on screen and thus a different design is required, we may associate this with our smartphones but they also work for mouse/keyboard input.

I know large screens can have touch. I'm asking why they are sending the instructions for rendering a page requiring touch controls to devices that don't have touch interfaces. (Seems like a waste of bandwidth, but maybe it ends up being insignificant overall.)
