iFixit has posted a thorough teardown of the new Apple Magic Mouse. The Magic Mouse is Apple's first multi-touch pointing device.
Notes: - The Magic Mouse is composed of an aluminum base topped off with a smooth multitouch panel, giving it a lustrous buttonless appearance. - There's not much Aluminum in the mouse, we weighed just 10 grams. That's compared to 37 grams of plastic and 47 grams of batteries. Nearly half the mouse's weight comes from the two AA batteries. - From the Apple logo up, the entire surface of the mouse is covered with capitative touch sensors. - Here's the Broadcom BCM2042A4KFBGH chip that allows the Magic Mouse to talk to its host.
