Recovering from a disk failure on laptop and having to reinstall everything... it got me to revisit the Adobe Suite CS5. Hard to believe Photoshop is over 20 years of age. The feature list of such a mature program (12 versions) has to either get shorter but more extraordinary or branch into new areas.
There are a number of new features in this version making it worthwhile: Edge Detection, Content-Aware Fill, Puppet Warp, 64-bit for Macintosh, enhanced 3D features (Extended only), painting and brush enhancements, enhanced HDR, auto Lens Correction, Mini Bridge, and numerous other small enhancements. I have to say content-aware fill and sizing is amazing.
