I think what you may be looking for is a device that allows you to type in text without requiring a surface on which to place it (while seated on a bus, lying down in bed). I've always wanted something similar myself, but mobile keyboards don't make it easy for you to type without having to focus your gaze directly on the keyboard. Perhaps someone could invent a device where your hands rest on a keyboard while the screen rests on your hands?
