One of the most important benefits of having layers is that you can do all your editing on a copy of the background layer which can always be deleted if you want to go back to the image's original state.
However, Lightroom does all it's editing LOSSLESSLY so the original file is not altered. Lightroom offers so much more, though, than image editing. It is really a DAM (Digital Asset Management) program with RAW and JPG editing facilities. I wouldn't be without it. I seldom need to use my CS3 or Elements 5 any more.
I'm a newbie to digital imaging too. I bought Elements 6 because it seemed to be the one that everyone used and talked about in the mags. Free tutorials and the like. I am waiting for the local schools to announce evening classes as I have found the whole thing very confusing. I have been unable to decipher the language in the Idiots book and am very dissapointed with my progress. As for layers, well this is really difficult for me to get to grips with. I understand the principle, but in practice it's just not working for me. So those who have said that a more simplistic approach to begin with, excluding layers are probably right. Good luck mate.
