Im actually using one of these right now. I got mine specifically for my laptop. I hate using the touchpad for EVERYTHING. So I saw one of these a the swapmeet and picked it up for four bucks. It is so simple to use. Ergonomically designed so your hand doesn't get tired or sore after hours of use. You basically slip your index finger through the hole that you hold it by. Theres a button on the inside of the hole that serves as the main button. The trackball is maneuvered by your thumb and it has two button right above that. One for the right click and the other one.......well, I haven't figured that out yet. lol. I just plugged mine right in and it was ready to use. So simple and extremley convenient. If only you could type with it! Its perfect for laptop users, if your tired of wearing out your touchpad.
