You could easily be a politician, with that spin on it
My finalized saves are jpegs, because that's what most of the printing places take. (along with TIFFS) I haven't seen any that take RAW files, nor would I want to upload such beasts for no gain.
So my finalized jpegs take up much less space than keeping all the RAW files around does. (and no, I don't nuke them, I archive them, in case I want to do something later - but they don't waste space on my HD either)
I really wanted to like Lightroom, but the fear that one small corrupt file or one small corrupt folder could destroy a whole lot of post processing work made my stomach churn. If I've got a final copy of the post-processed image on hand (that any number of other programs can read) just makes me feel better.
And don't get me wrong, I'm not saying Elements is better, hardly. Just for me and my workflow, this is what I've got and I like the way it works, that's all.
