Lightroom

Adobe Photoshop Lightroom has graduated from beta, and has sucked a $200 pre-order out of my bank account. I've been using the beta for over a year on both Windows and, more recently, the Mac. I'm sure Aperture is nice, too; but the tools and features of Lightroom met my needs and the bounce across platforms didn't require re-learning. I use it as an image library and a RAW processing engine.

Now, I just have to wait for Photoshop CS3 to come out, and I'll be in image-manipulation Nirvana....
