Before you bring your wine out to play, you might want to give it time to stretch its legs. After all, you don't jump right out after a six-hour car ride and run a a marathon, do you? Decanters are a middle-man from the bottle to the glass, allowing the wine to breathe between pours. They're also designed for a cleaner pour, unlike those ungainly bottle openings. Besides, a wine decanter just looks better than a boring, same-old wine bottle.
