So THAT's what that is...
Alrighty then.

I first saw one in my local Burger King and thought 'Why?' because you have to touch the screen several times to get what you already know you like. I later learned that the machines were gathering data and releasing popular flavors in bottles at Publix.
The ones I've personally tried: Didn't like Coke Vanilla or Sprite Vanilla. I do like Sprite Cherry, Sprite Orange, Sprite Grape (has a tangy flavor that's not in standard grape soda, and probably isn't as unhealthy), and a mix of Sprite Cherry & Vanilla (one website calls this 'Cherry Sundae'), using about an inch of vanilla since it's pretty strong.
I don't really drink soda other than Sprite or Root Beer so chances are I won't be trying other flavors.
