Is single-serve drink machines adding more packaging waste?

Imagine making a 12-cup batch using the traditional coffee maker.  Excluding the ground coffee itself, other than the energy and water used in the process the only environmental impact is the filter, which can probably be compostable or recyclable without issue.  Now consider a Tassimo or Kuerig machine, how much packaging would you need for the 12 little capsules?  Those as far as I can tell, aren't easily recyclable.  It at least requires cutting open the K-cup or T-disc, disposing the grounds as organic waste, then somehow recycling the shells, on which I don't even see any numbering.

Certainly we're not talking about taste/utility here.  Plenty of people stand by the quality of single-serving drinks (while many disagree as strongly).  From environmental point of view, I feel it's questionable.  Maybe there's some energy saving to be realized if you live alone and need just a single cup to get you going, but for many other situations, the packaging issue surely looks like a waste to me.
