Sometimes the home button on my rMini isn't responsive when I give it a quick tap. When this happens, I have to press it down all the way, almost as if I was long-pressing. It's not consistent, and the same thing happens with my iPod 4th Gen. I've just learned to live with it, especially since I usually use the 4-finger pinch gesture to get back to the home screen anyway. Just to clarify, this is a different issue than what I've read here before about the home button occasionally sticking. Has anyone else dealt with this?
