I have to agree that those are beautiful buildings. Though I like much of modern architecture anyway, with it's emphasis on simplicity. And at least in modern architecture, beauty and skill are still considered virtues, to my knowledge. OTOH, some of the stuff I see going up around here in Miami is pretty awful.
I have to say that as close as I've ever gotten to Miami is watching CSI: Miami. I have never been a city person, but I must say the producers sure make Miami look beautiful and glamorous there.
