I really enjoy soft drinks (terrible ik) and will never buy plastic bottles or cans instead of glass bottles. I really don't think I'm crazy or alone in thinking glass-bottled tastes better. My local convenience store sells Jarritos but not the glass-bottled Mexican coke and as a direct consequence I only buy the Jarritos, otherwise I'd mix it up a bit.

I assume glass is also better environmentally but I do wonder how much of the benefit is offset by taking more energy to produce (I assume) and to ship.
