Several folks have said Nitrox increases bottom time and reduces nitrogen loading. Actually it does either or, not both. If you're at the NDL on Nitrox you have the same amount of nitrogen in your system as when you're at the NDL on air. One can increase bottom time or increase conservatism to NDLs with Nitrox.
I don't see the point of requiring dives for Nitrox certs. Its all about the MOD and being able to analyze tanks (and be able to accurately reflect the mix on your computer.)
