I initially said many of the same things as the article writer, but since then I've seen several applications that work. One was an office where everyone drinks cans of sports energy drinks, but they needed some way to serve fresh coffee to clients. Another was an elderly woman who can only have 1-2 cups of coffee a week.
So I do see the value now. I think it helps to get a reusable "cup" for them:

As for me, I have a little 4-cup Black & Decker machine ($17.50 on sale) and have been trying to switch back to tea.
