Who really uploads raw, unedited, uncompressed HD videos anyways? I would think the vast majority of people wanting to share HD-quality videos would do some type of editing on a Mac/PC before sharing online.
You really can't see the usefulness here???
Okay, say your on vacation taking a bunch of awesome videos but since your phone is loaded up with all of your music and movies that you want to watch on the plane and in the hotel room, you have no space to keep more than 1 or 2 of your own on the phone unless you can offload them somewhere. And let's face it, taking your laptop on vacation is pretty lame.
The bottom line is, who the hell cares why someone else wants to do it? There are many reasons, and the technology exists so why not implement it? As someone else already said, Apple hasn't figured out how to make more money off of it yet.
