You're taking more risk not updating firmware than you are with an update.
Firmware typically contains fixes to problems and minor performance enhancements. Some are problems that are identified in development or with technical support but too late in the process to include with earlier updates or the initial firmware. Others are fixes to problems with the way the camera operates. One a camera is nearing production, software changes are only made via firmware updates - they will not modify firmware late in development as it would require significant testing.
Past fixes with Nikon cameras have improved battery performance, stopped hot pixel issues, and eliminated complaints about lens communication with the camera. Just because you have not run into those issues, does not mean you do not have problems that would be addressed by firmware updates.
Outside of user error during installation, I don't know of any problems from installing firmware (okay - there was one that was replaced with a new firmware within a short time).
