Outside of the lower profile, betting it is capable of higher charge rates needed for upcoming power hungry devices (remember you heard it here first, had an epiphany this morning). This alone is the only thing that makes sense if you think about it, why throw away this much compatibility unless there is a hard requirement that must be met. This is typically Apple fashion with smoke and mirrors telling you it makes it skinnier, etc. as opposed to telling you it is a power hog (less environmental).
