Probably because USB is slow.
USB 2.0 is 280 Mbit/s (35 MB/s)

USB 3.0 might be an alternative in the future, but it's fairly new. Then again, the USB 2.0 subsystem is used on iPhone 5, so the actual interface layer is lightning in order to allow it to be smaller.

or use the built-in airplay mirroring features of the OS :)
iOS 6: double-click home button, swipe left, and select display

It's an adapter/dongle, not a cable. It's the same shape adapter/dongle as VGA, and other adapters/dongles.

Have you been outside? Seriously...

Well, there is a difference between accent and just fucking it up completely.

There are people that I have spoken to that have such a light 'r' that it's nearly completely 'ah', and at the same time cant seem to speak some words without nearly eliminating the vowels, or making it choppy and cupping their mouth...
I figure it this way, slow down just a little and enunciate.
