I never really took my mouse's height into consideration until I saw the Eclipse Mobilemouse. This mouse has a built-in kickstand that lets you compute with the mouse flat or at a 45-degree angle.
The Eclipse Mobilemouse also features a scrollball that can move in all directions, not just up and down. Whether you're on the computer for hours at a time for work or simply clicking around for leisure, you should definitely check this mouse out.
