ARS Technica reviewed the new Mighty Mouse from Apple but they also decided to take a look at internal parts of the mouse.
Once we separated the top and bottom halves of the mouse, things started to get exciting. On the bottom half of the mouse, we observed the presence of a speaker (yes, it's true!), switches that trigger the side squeeze buttons, the mechanism that generates the main click of the mouse itself, and even an empty spot with a symbol showing where a capacitor would be (hmm, what sort of Mac rumors could we start with that one?).
