There's already been a lot of words shed discussing why the iPod nano 5G got a camera and the iPod Touch, much touted as the iPod set to get snapping skills didn't. The most common explanation was that the camera module simply wouldn't fit in the slim line shell of the iPod Touch. That doesn't seem to be true. The module in the iPhone 3GS is about 6mm thick and the iPod Touch is 8.5mm thick.
US iPod repair company, iFixIt, have gone all Gunther Von Hagens with an iPod nano 5G to reveal its inner-workings. It turns out that the beautiful looking beast is glued together inside and that the camera module is considerably smaller than the one inside the iPhone 3GS (which also does stills).
Kyle Wiens of iFixit told Wired.com that the camera module in the iPhone 3GS is thicker than the entire nano: "The AF lens really bulks it up." The camera in the iPod nano 5G is a seperate module and not built on to the device's main circuit board and it's just 3mm thick.
Another random and super-geeky fact from iFixit's teardown? The iPod nano 5G's screen has four times the pixels of the original nano's display.
