The latest BlackBerry devices come with an optical trackpad rather than a trackball. This is great for a couple of reasons: you no longer have to replace your trackball after wear-and-tear, and it looks way cooler.
Inside BlackBerry interviewed David (Vice President of Handheld Products) and Derek (Electronics Designer) to get more details about how the trackpad works. Basically, the optical trackpad is an optical mouse, except your finger is the the desk and you’re moving the desk.
