Is Later Mouse Better for Gaming?

For gamers, laser mouse may be worse. Here's a simple test you can do.

Lift your mouse slowly up, but try not to move the mouse.

Pick up your mouse and press your finger in the laser hole. For some laser mouse, you'll see the pointer jitters randomly, even though your finger is pressed in the hole and absolutely still.

This means, when gaming, when you lift the mouse to re-position, your pointer may move while the mouse is up.
