I was kind of thinking where is a good position to put a camera in the ipod touch 3G? I noticed if apple doesn't change the chrome back, will the camera be "heavily exposed", or will the back of the ipod touch have a "plastic-like covering" like the iphone 3G or S? also will the camera have zoom? and how many Mega-Pixels (i.e 1.3, 2.0, 3.0, 3.2?)
