Not sure if this has been posted or talked about. But I was on m.youtube.com earlier and noticed the HD option for videos. I just tested it out on 3G and it looks exactly as if it was straight off the computer.

I wonder what resolution it's actually loading for the videos. If it's actually HD that's overkill....
I would think in this case it's still scaled very small. They are probably using HD to mean it's not so compressed it's painful to watch. Like any other YouTube video I've ever seen on a mobile that is.
