Has low-carb gone too far?

First living a low-carb lifestyle meant giving up things like bread, cola, and beer.

Now, there is Atkins-approved bread.
Low-carb beers (which are just light beers re-packaged and more expensive)

And now, I give you low(er)-carb Coke.

Coca-Cola C2

I saw it in the grocery store yesterday. Does it have few calories than diet coke? Because you can already have diet coke (or soda for those non-Coke drinkers or non-Southerns - everything down here is coke) on South Beach...

Diet Coke with lime is pretty tasty.
