Many laptop owners carry a spare mouse because they dont like the built in control, or because they just like to use a mouse. This adds weight, things to remember etc when you go anywhere. Also, if you use somebody elses laptop you may not be able to use their pad at all! I often setup software for somebody else on a laptop and curse the wigglestick on the keyboard that they fumble on with because they are that slow anyway but it holds me up. If I had a mouse with me at all times that would be amazing. So, the NokiaMouse was born.
