So, looks like that wireless trackpad peripheral that’s been rumored and leaked has become official, and it’s called the Apple Magic Trackpad. It’s basically a larger version of the trackpad found on the Macbook Pro. Aluminum, glass-covered, and multitouch. It communicates with your Mac over Bluetooth, takes two AA batteries (included,) and requires Mac OS X Snow Leopard 10.6.4. You can pick one up now for $69.
