XXP4 is great! At USD50 for the upgrade, it's a bargain and I have bought it.

The Canon 40D's RAW format is hopefully now more easily available -- it would be really great if XXP4 would display it properly instead of as a mainly magenta image. I can do just about everything I need with Elements 6, but some things would just be so much easier (and more fun) with Xara's features.
