Amazon.com is selling Lightroom 4 for $99 right now. That’s $50 of the regular price, and less expensive than I’ve seen it anywhere else.
After starting out using Apple’s Aperture 3, I decided to give Adobe’s Lightroom 4 a try, mostly due to the fact that it seemed most serious photographers preferred Lightroom to Aperture. I’ve got to tell you – I love it! Once I’ve had more time to get comfortable with Lightroom, I’ll explain what I like better about it, but if you are thinking of upgrading to a more powerful photo management / editing program, I’d recommend going with Adobe Lightroom 4.
