why would anyone want to use it? I see nothing wrong with just typing directly from the device. It is so easy typing on it. why spend the money for a keyboard? it is a smartphone and it is equipped to be simple and easy. If you need a keyboard why not just use your laptop?
Why not try to help instead of deflecting the question? A Bluetooth keyboard will work. I don't think a mouse would, since there is no cursor, but the keyboard will.
