Anyone Else Notice People Going Coconuts?

I am starting to see ads everywhere for coconut water. I tried some the other day and was not that impressed. Maybe there are good health benefits though? It seems as if this came out of no where as I had never heard of it until a few months ago and now there are ads everywhere. I just saw one on the homepage of my email and a billboard went up on the toll way.

What are your thoughts? Anyone tried the different brands and can say if they differ in taste? The one I had was a light blue packaging in a small screw cap bottle. I forget the name at the moment.

Ah, I found it. It was Zico.
