Does Tassimo plan on having a reusable disc/pod filter like the reusable k cup filter that Keurig has come up with? This would be so helpful for those that want to use other coffees/teas, etc. that are not available in pods. And also for those who may want to regulate their strength more extremely than others. I saw that there is one for Senseo machines (i.e. Ecopad). Would that one fit the Tassimo? I am trying to determine which coffee maker meets the needs of mother, and having that filter is a plus for her.
