And after years of training the Grand Kids to keep their dirty little paws off the walls, windows, TV and computer screens...
Never mind the kids.
Nobody's hands are clean and oil-free enough to prevent the need for non-stop screen cleaning. Don't know about everyone else, but I enjoy knowing if that's a decimal point or dust/pizza/danish/donut/potato chip/ residue up on the screen.
Whose bright idea was that touch screen stuff, anyway?
