Why Have a Photo Booth at Your Wedding?

I've had several friends suggest that the photo booth thing is getting old and we should of new, creative wedding ideas. While I love to watch the booth evolve, I can't say that I agree with it being obsolete. I just don't think it's gotten old, as much as it's become popularized and "trendy" it seems that no matter what event you put it at, there's always a boat load of peeps coming to take photos. So to there person who says that photo booth is going out of style, watch the line next time your at wedding photo booth.
