Having the two options for our office was the main reason for getting this coffeemaker. The 12-cup option is good for the morning 'coffee-run' but as the day wears on, the single-cup option is more efficient and economical. The Senseo pods are not as easy to find as the K-pods. And having to clean out the wire filter every time is not as convenient. It would also be better to have a large transparent water container on the side instead of having to fill it up every time with water, especially for single cups.
