Just saw this article on Slate. I thought it was interesting from a couple of angles. I don't use these sorts of products, but if one came along that really didn't differ much from the real thing and was cheaper, then maybe I'd start thinking about it. The other interesting aspect of the article was the company that's producing this stuff. They're pretty ambitious.
Thought I'd post it and see what everyone here thinks about these products in general and the one described in this article in particular.
