The release date of the "iPad 2," which Apple Inc launched in the US March 11, 2011, has not been determined yet for the Japanese market due to the earthquakes.
However, Nikkei Electronics Teardown Squad obtained a white model, which is not available for the first-generation iPad, in the US and disassembled it.
The first impression we had was "It's slim" rather than "It's light." While the back of the first iPad is curvy, that of the iPad 2 is flat. And the rims of the iPad 2 are wedged. Even though the actual thicknesses of the iPad and the iPad 2 are 13.4 and 8.8mm, respectively, we felt that the iPad 2 was half as thick as the iPad.
In terms of functions, the largest difference between the first-generation iPad and the iPad 2 is that the iPad 2 has two cameras on its front and back sides. And it is equipped with camera-related applications software as standard features. They include an application that adds various effects to images taken by the camera in real time and displays their thumbnails on the large screen at the same time.
After briefly checking the iPad 2, we began to tear it down by bringing in a first-generation iPad that we disassembled before for reference. The back side of the first-generation iPad's front glass is reinforced by a resin frame, and the frame is fitted in an aluminum alloy frame.
We started to pry open the front glass of the iPad 2, assuming that it has the same structure. But this turned out to be a wrong decision.
