No unicorns inside Apple's Magic Trackpad

iFixit cracks one open to see what's inside the latest Apple gadget

The fine folks over at iFixit have done another Apple teardown, this time of the new Magic Trackpad, which is part of the new iMacs Apple introduced earlier this week. Sadly, the iFixit team "didn't find any magical unicorns inside," but they were impressed on how the Apple engineers were able to pack lots of stuff inside a thin profile.

Some of the other highlights:

* This is one of the few Apple products where the battery is user serviceable. * The battery screw has square threads! While square threads have the highest mechanical efficiency of all lead screws, their difficulty of manufacturing makes them prohibitive for most applications. Kudos, Apple, for sweating the details. * After a good amount of quasi-non-destructive prying, the inner spacer can be removed from the trackpad. This spacer prevents the highly unlikely event of squeezing the lower panel against the logic board hard enough to damage it. * The ribbon cables are ridiculously thin and are stuck to the underside of the touch pad. If you plan on servicing your Trackpad, proceed with caution. * After using a heat gun to warm up the adhesive, the touch pad can be carefully pried off the aluminum chassis. This step is not for the faint of heart. A copious amount of heat, guitar picks, and plastic opening tools were required to make the touch pad budge. * The Magic Trackpad has a unique way of triggering the mouse button. As you press down on the top surface of the pad, the two rubber feet near its front edge push on a plate attached to the chassis. The plate squeezes the electronic mouse button switch, producing the characteristic "click."
 * At the heart of the Magic Trackpad's logic board lies a Broadcom BCM2042 for Bluetooth connectivity -- the same chip used by the Magic Mouse.
 * We also found a Broadcom BCM5974 touch screen controller chip that provides multi-touch functionality. This is the same chip you'll find in the iPhone, iPod Touch, and MacBook Air.
Phineas and Ferb find a unicorn, still waiting for Apple

Of course, if anyone is going to discover/find/harness a unicorn, it's gonna be the Apple people, right? Or Phineas and Ferb (pictured, for those of you without P&F-obsessed kids).
