I've used DNG files since the beginning. During import, I save a copy of the NEF file to an external drive, just in case, but I've never needed them.
I particularly like the idea that all edits are stored within the DNG file, as opposed to LR writing out a separate XMP sidecar file.
I agree with Bruce. Saving your original file and DNG file with any changes you may have made in LR is probably the best way to go but who knows what the future may bring. Though I believe if sometime in the future someone comes up with a better solution or should Adobe abandon DNG that any number of software manufacturers will come up with a converter to the new "improved" format. ;)
