I have always loved my iperespresso machine.  When my last one broke, illy replaced it and I immediately noticed a difference.  The espresso flowed a little faster and smoother, the crema on top was thick and lush and the complexity of the coffee was enhanced. I don't know what the difference is but I even enjoy the espresso straight up, because of its rich tones of caramel and fruit.  I've dislike "pod" machines, others produce flat and insipid brews.  The X7.1 is nothing like regular pod machines. And I love that  Illy sends a bag so I can send pods back for recycling.  Never settle for less than Illy.
