In the grand tradition of TMI, the G1's gone through a teardown for your voyeuristic pleasure. Underneath that chubby matte shell there are all sorts of build-related details that you probably didn't need to know, like the fact that Panasonic built the main board, the compass was built by Asahi Kasei (exciting, we know) and the keyboard element is thin. Some might say too thin. Perhaps of most note is the trackball, which is basically identical to what RIM uses -- minus the fancy glowing effect. All riveting factoids, we assure you. One item of worry is that the engineers doing the teardown noted the particular thinness of the plastic bar connecting the sliding display to the phone, and raised the troubling possibility of breaking the display off from he handset. We certainly won't be stress testing that element, we can assure you.
