I got Micosoft Wireless IntelliMouse Explorer present from my dad, and installed it on my computer. I loved it. Very Comfort. The features: wireless, optical, five programmable buttons, ergonomic design, and improved the longer battery life. The mouse has a new feature: tilt wheel for side-to-side scrolling. This is very neat, and can be very useful in Macromedia Flash or Director to scroll left & right on timeline (Flash) or score frame (Director). I gave my 3-year-old Microsoft IntelliMouse Explorer away to my brother, Billy.
