The gadget-smashers at iSuppli have cracked open and indexed the iPod Touch’s parts, and found that it’s more than a crippled iPhone (some would say the iPhone was crippled already, but that’s another story.) The parts used are 90 percent the same, they say, but the iPod Touch has a more unified design. It uses a single PCB for one thing, and the touchscreen and a different WLAN component are attached directly to that, instead of to a separate PCB in the iPhone. Some of the components were entirely new to the iPod’s destroyers, and a huge amount of care was taken, as one might imagine, in compressing everything into the smallest space possible. So when someone tells you your Touch is just a iPhone Minus, tell them about the streamlined circuit board design and remind them that it’s thinner as well. Then maybe an Eskimo kiss so they know you’re just playing around.
