it probably frees up more room inside the device. for battery? storage?
the headphone jack is now on the bottom now, so if they had to budge the 30 pin across and make it off centre it would have look ****.

Who knows??, but apple wouldn't have done it for no reason would they
having had the old connecter for what nearly a decade?... jeez use your brain a little instead of concluding it does **** all when its not even out.
