As we mentioned above, the touch now features the same Retina display technology you'd find in the latest iPhone, which gives the screen a much-improved resolution of 960 by 640. The touch also features a gyroscope, just like the iPhone 4. Apple likes to tout the iPod touch's prowess as a gaming device, so these features seem like natural fits and should be welcomed by gamers--the Retina display will mean improved graphics while the gyroscope promises to bolster gameplay.

The new iPod touch also gets an upgrade to 802.11n wireless (from 802.11g in the previous model), but only the 2.4GHz flavor, not the full 5GHz version that Apple uses in its wireless base stations. Oh, and the touch now runs on an Apple-designed A4 chip, which the company says will improve performance and extend battery life to the tune of 40 hours of audio playback and seven hours of video-watching.

No. That's one of the few hardware features still reserved for the iPhone.
