Not surprising battery life isn't very good considering the leak is based on a test build that probably hasn't been fully tweaked yet. That or ICS and the new Sense 3.6 is hurting battery or it just takes time for things to settle. Either way from what I've read about this leak and seen with ICS so far, I'm still content to stay on Gingerbread and older Sense 2.1.
Thanks for the screen shot. That's a cool background! Although I have to agree with others that new dock is ugly and takes up too much room. I know the older curved dock is less customizable, but IMO just looks better. Wish it was still an option in the new Sense 3.6.
Oh, btw, just curious; can you get rid of that Google search widget/bar? It's not static on every screen is it?
