People have asked me why I need a mobile scanner when I have an excellent camera to photograph documents, pictures, etc. This serves a slightly different purpose and is ideal for my family history research, also it's great fun (and easy) to use.
Nice case and ideal to protect my iPad but the keys are very difficult to use. I am a touch-typist but these don't respond to the touch - they need quite a lot of pressure to make them work. Very disappointing.
