Starbucks is really pushing this espresso machine.

It has a lot of features for $600. The auto-tamping feature is good for newbies but is only good for mediocre espresso. The crema looks thin in the video. A proper espresso machine makes crema that comes out with the viscosity of warm honey.
The dual boiler is a bit misleading. You still can't pull shots and steam at the same time.
The temperature gauge is interesting. There isn't a scale to indicate what the actual temperature is, only whether it's in the zone or not. I can see where that idea came from.
Not a bad machine though for the price. However, I like my espresso machines like my cars - manual not auto.
