For a moment I was hoping there was a replacement for the wonderful (and ancient) Microsoft Trackball Explorer. If you are right-handed then it is ergonomically shaped to fit your hand. Use your fingers to move the (large) ball and your thumb to press the buttons. Comfortable and natural to use. The fact that refurbished models sell for very high prices shows just how good they are.
