lifehacker. Adobe Lightroom Beta is a photo management and editing software touted to be "better than Picasa" (!!!). The screenshots definitely look convincing. The user interface looks very pretty and streamlined. The Beta version is free so make sure you give it a try. As soon as I return home from my oncalls I definitely will!
