The smart cover protects the screen from impacts and scratches. I don't care so much about the back. A scratch on the screen would be a major annoyance. A scratch on the back would easy to live with. Besides, in a year of use with a naked back my iPad hasn't even gotten a scratch. I think if you're reasonably careful where you put it down, you'll find that the metal is not as delicate as some folks would have you believe. With the smart cover on it the best position for it when not in use is face down.
