Wow, after reading a lot of your comments, I can't believe how shallow this forum is.
I would never knock on a person's choice for their wedding bands; it's a symbol of a life commitment, not a symbol of your pocketbook (which is what an engagement ring is).
Wedding bands are plain, timeless, and classic. They aren't supposed to be flashy. I couldn't tell the difference between a white gold, platinum, stainless, or tungsten band just by looking at one, nor would I care.
Tungsten seems unique, and it has properties that make it desirable (extreme hardness, lasting polish). I might look into getting one myself when I get married. I'm sure the S.O. will still want a platinum band to match her engagement ring, and that's fine.
