This document compares and contrasts the Keurig and Tassimo single-serve coffee brewing systems. It discusses the cost of the machines, cost per serving, number of drink options, and how each system works. The Keurig offers more drink varieties and lower per serving costs while the Tassimo allows for more customization but is less environmentally friendly. A third option, the Y1 Francis, is also introduced as providing a superior espresso experience for true connoisseurs, but at a higher price point. In conclusion, the Keurig is determined to be superior to the Tassimo overall.
