Clunky touchscreens are easier to use than slick ones

Pretty doesn't equal usable. "When I worked in food service and in the mailroom, the uglier touchscreens were always easier to work with. They were color coded with bright, contrasting colors, making the boundaries between numbers or items very obvious. I found that the colors reduced mistakes. I’d usually tap the right items after barely even glancing at the interface. After a while, I’d only check the screen for mistakes at the end of the process, before submitting an order or printing a receipt."
