I'd would prefer the new one if it were dynamic, but the old one otherwise.

I think once you allocate horizontal space on most 16:9 screens, you might as well have it full height.

To collapse the current inspector to its title bar is dumb, just show/hide it with toolbar or keyboard.

I still think that most of the inspector should be moved to a context sensitive toolbar ala iWork 08 (while keeping the full set of stuff in some form of inspector ala iWork 08).
