DNG the RAW answer

I've been playing with ways to minimize the D600's impact on my hard drive space and just began copying and importing as DNG to Lightroom rather than keeping the files NEF. Not only does this save a few megabytes of space per file, but the previews load MUCH faster. I'm talking probably 3-4x as fast. I did a little digging and it looks like Adobe has been hard at work making DNG the best RAW option: http://news.cnet.com/8301-30685_3-57371809-264/adobe-offering-new-reasons-to-get-dng-religion/
