I'm not saying that it's bad, simply that you cannot compare the two, they don't produce the same coffee.

Apart from that, what Keurig is doing (Nespresso is doing the same in Europe) is just plain wrong and should be prevented on a legal level. In France we have this "interop" law that allows us, for the sake of interoperability, to reverse-engineer a patented system to use with non-standard consumables. We have these capsule-based espresso cups, but anybody can sell the capsules.

If you want a real espresso, though, one that doesn't lock you up in a franchise and DRM-ed capsules, just buy a normal espresso machine.
