It is mid-February, and you know what that means: Adobe today announced the immediate availability of it's competitor to Apple's Aperture, Photoshop Lightroom. Version 1.0 includes the updated Camera Raw 3.7 framework which adds support for a number of new cameras including the Nikon D40 and Pentax K10D. Lightroom is available at a special discounted introductory price of $200 until the 30th of April, after which the price will increase to $300. Current users of the Lightroom beta can continue using the software until the 28th of this month.
I've been using Lightroom since I picked up a Pentax K100D back in December, and I absolutely adore it. The interface is beautiful, it runs pretty darn well on my aging PowerBook, and it seamlessly integrates with Photoshop CS2. Now I just have to figure out how to work the automated processing features and I'll be golden... once I find the cash to pay for the full version.
