Ok, assuming that this Sneak peek of Content-Aware Fill in Photoshop is included in CS5, that's totally worth the price of admission, says the photographer in me, especially the one that loves panoramas. Watch till the end to be sure.
If you remember the Content Aware Scaling from CS4, this is sort of the opposite, basically the ability to fill in an area that has a non-simple surrounding. Healing brush works well for the simple case (ie: a dot on a grassy lawn), but if you're trying to do something more complex, it's a huge PITA. This looks to be an epic addition to your photographers toolbox.
