So far the PDA site seems to work quite well. Would be great to have the post date inside the threads - maybe in the blue header next to the poster's name.

The only other thing I've noticed so far is just a personal visual preference. I find there is not enough differentiation between the threads on the New Post search results. Maybe a little more white space, or a little indent on the last line of the thread description - the one with the last post date.
