This debate reminds me of the time when digital instruments, esp. 
tachometers first became available in the motorsports world. The digital
tachs were faster responding, more accurate, and "tricker" than their
analog counterparts. However in short order they dissappeared from the
scene. Why? Because it is significantly more simple for the brain to
quickly interpret the relative position of a needle over a texual
display.

While a diver doesn't have to hit a shift point at just the right 
instant I do think that there are simularities in the two cases 
especially when narcosis sets in. I've had times when I've rather
dumbly stared at my computer while my brain tried to interpret what
those symbols in front of my eyes mean. I have no doubt that in the
same situation some sort of an analog display would have been more
meaningful, if perhaps a little less accurate. All in all I have no
desire for an air integrated system.

Just my $.02 worth.
