I was very amused one day in one of Sun's offices to see a big eco friendly poster of some sort--this was during their green computing kick--right above one of these pod/packet machines.

It's tough in a big office though unless someone's keeping the coffee made and fresh as is the case in a meeting setting. People take the last cup and don't make fresh coffee or they just don't want to wait.

We have both a coffeemaker with thermoses and a pod coffeemaker which seems a reasonable compromise.
