Love it :-)

Do you mean do I download it to my PC?  Absolutely.

If I am not mistaken, it is designed for a single mixture in one dive.  I
don't have the manual here but I don't think that it was designed to make
gas changes under water.  It is very easy to change mixtures on the surface
(of course if you did not forget to enter Nitrox mode before your first
dive in a series).  The only downside is that it is designed to go back to
Nitrox 21 after a couple of hours (as a precaution I guess) so you have to
fiddle with it before every dive.

As I said, I think it is not possible to switch under water.  The new Vytec
is supposed to deal with up to three mixtures.  I haven't tried it.

I don't like air integrated computers so the Cobra is not an option for me.
