Greetings, Greg!
I’m not sure you interpreted Chris’ comment correctly- he’s basically saying that he thinks the Keurig is a good investment for folks who like coffee but don’t necessarily want an entire pot. In fact, he’s bought Keurigs for his Mom and girlfriend on that basis.
That said, the reality is that coffee is not a necessity, as much as it might seem so for me 🙂 Like a lot of drink and food in modern society, it is a luxury. Drink it how you like it- if brewing a pot, or a single cup non-Keurig brewer, or a coffee press works for you, that’s great.
I wouldn’t recommend the Keurig to someone without walking through the math: what it really costs per cup, which is probably between seventy five cents and a dollar a cup. Nor would I recommend the Keurig for someone who regularly needs/wants several cups at once: a fresh pot is just as tasty. But for someone who likes a variety of different coffees, usually drinks one or two cups at a time, and who understands the cost- it can be as “cost per unit of enjoyment” effective as other solutions (E.G.: brewing a pot and throwing away some/all of it, buying brewed coffee from Tim Hortons/Starbucks/what have you, or not enjoying the coffee you drink).
