Query: It coudn't be easier

I got one of these from a friend and was surprised by the size - the ones I had seen were big as DVD remotes. Being a manual freak, I was a bit disappointed, but when I plugged it in the USB port I realized there was no need for a manual. There is storage bay inside the pointer that disables it, preserving the battery if the buttons are pressed when stored - clever!
