I have only just started using mine, so not a great deal to say yet.
One feature I really like is that you can set "focus priority" in "continuous focus" mode which won't allow shutter release if the subject is out of focus. The default "release priority" will allow you to take an out of focus shot.
Other than that, I like everything about it so much more than my trusty D70. Never thought I would say that after one outing with a new camera.
[edit to add] p.s. congrats on the 25 years (mine's next August).
