I'll drink soda out of pretty much any container--I'm really not that picky. Don't drink it every day but when I do it needn't be out of glass/aluminum/plastic either way.
Like many of the other posters, however, an aluminum or nickel alloy can imparts a metallic taste to the beverage inside. Glass is more inert and doesn't do this. I personally don't have the taste buds to differentiate between glass and plastic--they're pretty much equivalent to my palate.
I don't drink beer, but here in Hawaii we are close enough to the Philippines that every once in a while I am able to pick up a six-pack of imported coke in glass bottles made with cane sugar. Hands down, this by far and away the best tasting soda. My husband works for a soda manufacturer here on island and judging by some of his work stories, the plant here wishes they could afford to mass produce glass-containered soda made with cane sugar. Cane sugar's no longer a major agricultural product here in Hawaii (though it used to be), so everything that the soda plant bottles now is put into either plastic or a can. Incidentally, it turns out that cans are WAY cheaper than the plastic slips used to make bottles. I was also surprised to hear that the company uses the same size/density plastic slip to make all their plastic bottles, from 2 liters all the way down to 16 oz soda containers. This is why a 2 liter bottle feels much thinner than a 16 oz bottle.
