This thing does %87 of every thing I ever want to do with a digital image. Most importantly... it keeps them all ORGANIZED!! I can very quickly import batch of photos from a camera/disk, flip thru them, delete the trash, tag each image or a group of images, and sort them. Basic editing is possible. I can then publish them to a web site with a few clicks Generally I love it. Very simple very fast. The big weakness for me is weakness of the editing tools. Which brings me to Adobe Lightroom:

Lightroom absolutely KICKS ASS!! Its still a beta but its quite stable on my machine.

You will love it.
