Andy, Using Lightroom I'm used to the crop tool, but must admit that second photo (once you get your head around the perspective) is something special.
I was playing with the Content Aware move tool last night. It has a few flaws but works very well in certain circumstances.
Example attached. the sand racer was one of a series, in this particular frame the rider was heading out of the frame on the right hand side a perfect photo for trying out the move tool.
One or two minor problems which could easily be corrected using a little more care/practice and such as the clone tool.
I like the interface and it's much faster than CS5, but the upgrade will have to be priced similar to Lightroom for me to upgrade.
