I'm not surprised by their popularity.<p>I'm going to set aside coffee <i>quality</i> for a second - because the truth is, the average consumer doesn't seem to care about this beyond a certain threshold, which judging by the popularity of these Keurig and Keurig-like products, the options clearly meet - and I want to focus on what it delivers.<p>What it delivers is <i>consistency</i>. You put a pod in, fill up the water as needed, and press a button. Rinse and repeat, and you always get the same specified amount of coffee. Its precision consistent. No making a big pot of coffee only to waste it.<p>Not to mention, its simple to clean up. Just throw the pod away. No grounds, no coffee filters, just pop the pod, and on to the next one.<p>As far as convenience goes, it hits all the notes.<p>It may not for <i>you</i>, of course, but the average consumer is still buying these systems and its only growing.<p>Given how cheap it is to make these systems, I'm really not shocked it went to the consumer relatively quickly and didn't settle as an office only thing.<p>Now, they are an environmental catstrophe, that is true, and thats a great reason to transition away from these systems
