On the heels of Soda Stream popularity, Coca-Cola decided that it's time to let go of its magic formula (well, not really) and allow people to make Coke at home. Or something very similar to it.
There's of course concern that people making sodas at home will undermine sales of Colas outside of the above mentioned homes, but so far this haven't happened in the coffee industry. People are buying their coffees-on-the-go like crazy. Just look at Starbucks.
