I am loving Lightroom and all the things that we can list about it that it doesn't do, I bet it will in future versions. I don't feel any loyalty towards Adobe but I do believe in their products and their commitment to improving those products. We can't always have all the features we need as we need them and for some people I know that Canon's DPP is preferred because their software presents you with information that is not contained within EXIF data... for instance, seeing your AF points.
Which program we use depends on our individual needs. It's like the comparison/argument about Lightroom vs. Aperture. They are both such powerful programs and it's just a quesion of which interface you like and which one lets you develop a work flow that, well...........flows.
