One comment that may be helpful to all new D4 & D800 owners.
If you are running a Mac, the Mac OS has already been updated free for both cameras' RAW conversion. It will read the nef files from the desktop. Current tools will do the job cheap or free, as many mac apps use the OS converter rather than write their own.
That means iPhoto, typically free unless you have a really old version, and Aperture 3 ($79.99, my weapon of choice) work perfectly with the new files. Now I already had CS5, but I only use it for complicated work, Aperture handles 95% of workflow without issue.
