I tested my new D80 for hot pixels (1/15 s, ISO400 with cap on, NR OFF) and found one blue dot.
It does not disappear at other settings, even at 1/60 ISO100 without cap. In this case it is white dot with a blue area around it.
I wonder what it is and shoud I bother to do anything about it if there is just one such pixel on the sensor?

Honestly, with 10 million photosites, this is bound to happen. Put simply, there is no surefire hardware solution, as a trip to Nikon repair facility for a remap is no guarantee that when the camera is shipped back to you a new hot pixel won't develop.
I sent my D80 into Nikon repair Melville facility with 0 hot pixels, and it came back with a pixel so hot it can be seen in basic quality jpgs. It says in the repair they upgraded the memory compression... oh well. I simply accept that, no camera is perfect.
Your best solution is a software raw processor that filters hot pixels. There are quite a few software packages that do this. And of course, there's always the clone stamp (gasp).

Thanks for the answer. There is an authorized service center in my city, but I decided not to go there for remapping. I called the shop and luckily they let me come and change that camera for another one and let me test the new one in the shop to my complete satisfaction.
