Yup, and most electronic devices have a power button.
Although, you don't hear many people claiming that their device "features" a power button. No, it is just standard.
Was the door on your house one of the highlighted "features" during the pitch? You would have laughed at real estate agent if they told you the house "features" a door. Of course it "features" a door! You would be befuddled if it didn't. Kind of like how I am befuddled when a computer doesn't "feature" printing or spell check. (Although they do have spell check now)

But anyway, nice arguing with you. I have made my point and will now move on.
