I love the idea of a smart coffee machine, this one has potential but falls short.  Here are my issues with the machine: 1. It takes too long to brew, the need to detect the brew ID slows down the process. 2. The fact that you have to wait for the machine to finish brewing before you can frost also slows down the process.  3.  When the machine finishes frosting it doesn't alert, if you are not in front of it you won't know when it finished.  This causes the frost and the milk to separate or cool down. The previous model of Keurig had all these features. I am surprised that it didn't carry over to this newer model.
