He succumbed last month. I wouldn’t go so far as to say that I’m an addict, precisely: but it is useful to have a one-cup system where my wife and I don’t have to decide which kind of coffee we want to brew. It also makes regulating our caffeine intake easier, although that’s more of an issue for my wife than for me.
On the other hand, I liked making iced coffee out of the dregs of the coffeepot. Not a deal breaker, but there you go.
