iPod nano internals
After
Separately, iFixIt dissected the new iPod nano and observed that the unit's 3.2 mm wide dock connector "looks pretty big compared to the iPod" itself, making it unlikely that Apple will be able to slim down player any further without developing a new dock connector.
A particularly surprising find was that the new nano uses a real piece of curved glass, "about .7 mm thick on the edges, and 1.7 mm thick in the middle," to cover the LCD display. The glass is said to be completely separate from the player's anodized aluminum enclosure, with nothing holding it in place outside the force of the adjacent components.
The LCD itself "is actually almost exactly the same size as the 3rd Gen Nano LCD," iFixIt said, with the only difference being a resolution of 240x320 rather than 320x240.
Among the nano's internal components are a Apple-branded ARM processor manufactured by Samsung in July with on-board DRAM on-package, three other small Apple-branded chips of unknown origin, and an 8 GB Toshiba flash chip. "Unfortunately, the battery is soldered to the logic board," iFixIt said. "Replacing the Nano's battery isn't going to be easy."
