Interesting point about CO2 - I'd assume your thought about condensation is correct, but it also occurs to me to wonder if it's a gas in those little canisters; a lot of the gas systems I've dealt with have a liquid phase somewhere in the loop.

And I didn't think that carbonated beverages had any difference in flavor, but a huge difference in texture/mouthfeel.

Carbonated beverages have carbonic acid in them (H2CO3). Even after all the bubbles are gone a carbonated drink will be more tart than a non-carbonated version of the same drink.

So what exactly is visible in dry ice mist (see every 80s pop video)?

Edit: NM, Wikipedia says "condensing water vapor", indeed.

Yes, it's called dry ice because if you look at a phase diagram, a liquid can't exist at atmospheric pressure, so carbon dioxide ice transitions directly from solid to gas (called sublimating rather than evaporating/melting). One of those neat chemistry things.
