benefits of hydration through “tap” water verses bottled water

“In the world of sports, hydration is king, or queen.  The sports industry is fueled (literally) by mega companies who spend billions of dollars to sell us an amazing fuel that stains life, heightens performance, prevents, fatigue, and helps us regulate our own body temperatures.  That’s right:  we’re talking about water!  However, in the hands of a few nutritionists and some clever marketing people, we have been duped!  We buy more water in containers, than ever and we demand that the water be infused with “extras” of all kinds so we can “be better.”

Is this truly necessary?  Is bottled water/sports beverages that much better for you or are we all just victims of our own vanity?  Please respond to these questions with 50+ words on your opinion of this topic.
