I've been using an original Microsoft IntelliMouse ever since it was released. I love the non-mechanical infrared tracking. However, one thing I've always hated with the MS Mouse is the ergonomics. Although the shape of the mouse is comfortable, each button is edged with a sharp plastic seam, which does a wonderful job of shaving your fingerprints.
Microsoft has made plenty of improvements to the IntelliMouse since I bought the original one, but my new mouse is a Logitech Mx500 ![[B00006HZ0K]](http://www.mikeyp.com/css/external.gif)
. This is the most comfortable and ergonomic mouse I've ever used, even compared to the more expensive Logitech "Laser" mice. The shape is perfect for right-handers, and each button has a smooth rounded bevel that allows your hand to glide from click to click. The bonus "cruise" buttons above and below the mouse wheel are intuitive and an excellent alternative to using the mouse wheel for scrolling.
The Logitech Mx500 is also a perfect match with my Saitek Gamer Keyboard. What a combo!
