Computer users have different ideas as what accessory they prefer to use, in fact, it would seem that the some users like the mouse; while others like a track pad; it is just a matter of choice and in many cases lucky that most laptops have the choice.
However, no matter what might think about a touchpad, these days they are all different, like this one from Smart Track. This has been made to connect through the USB port, when once connected it supports multi touch gestures, the user can control what it does though different movements, it is a handy little device once you have got used to it.
