A new teardown of the iPod touch shows that it is not as similar to the iPhone as one might think, according to the research firm iSuppli. While cosmetically and functionally identical to the iPhone in many regards, such as in its “springboard” touchscreen interface, the iPod touch shows internal evidence of using a different design with some advancements.
The player has a single printed circuit board (PCB) instead of two, for instance, onto which the touchscreen circuitry has been moved as well. Similarly, new components have been put in the Touch in service of its Wi-Fi functions.
