I understand that the full size NEF file is about 36 MB. Although that is quite a bit larger than that produced by other digital 35mm equivalent digial cameras it is only about one third the size of 35mm film images scanned at 4000 ppi (the standard for scanning with dedicated film scanners). I have been working with such scanned images for some time on various "mainstream" computers, i.e. not a super expensive, super fast, machine. In my opinion, too much is being made of the "huge" size of the D800 files. Any modern computer should handle the files with no problem.
