The point isn't specifically being able to edit or export a video, it's that the iphone can do processor intensive tasks faster. I don't play games on my phone, but others do, so faster load times is something that a person who plays games on their phone might appreciate for that or any other intensive task.
To me it's like dimming sideview mirrors or AC seats in your car. If you've never had a car with them, you wouldn't know what you're missing out 'em.
I'm not trying to persuade anyone to buy an iPhone, I prefer android and the N8. Webos like gestures, the camera and the A11 Bionic chip (like I initially metioned) are why I would consider using both phones.
