So now the debate: Glass vs. Metal?

Glass seems more "trendy" and potentialy dangerous (glass from straw chipping into liquid while stirring?) than the metal however I'd also be afraid the liquids would leech some metal and alter the taste of a consumed beverage?

Um...no!

yikes

Bad for your teeth

Why can't we just drink from the glass?

Unless you are really good about rinsing things right away, they would be hard to clean.

I am guilty of using straws all the time because the ice hitting my teeth hurts :( but the other day I read this article and it said that straw sipping would later lead to wrinkles around the mouth like a smoker(not attractive!). That scared the hell out of me so now I don't use them as often.

i got scared straight!

for the sake of your teeth, don't try to chew at them

And how would you clean them?

Ridiculous!

I just have an image of somebody falling and somehow the drink stays in their hand and they fall on the straw or something. Painful.

Unreasonable imagery, I know, but I can't help it. Ouch.
