Summary: I got on board the Tassimo train back in '08, before the single-serve coffee craze had really taken off. I found the machine incredible and was basically a diehard fan, influencing more than a few people to try out the machine. Fast forward a few years, and I've dumped Tassimo for good. Why? Strictly comparing the brewers, I personally believe that the Tassimo is slightly superior to its competitor, the Keurig.
Summary: The product worked great until they stopped selling Starbucks and only offer their brand. You need to clean off the bar code reader every now and then but otherwise it made a very good cup of coffee.
Summary: I was debating between this and a Keurig. I bought the Tassimo becuase I liked the idea of being able to make tea and hot chocolate in addition to coffee. The reviews that I read said that it was really quiet. I haven't found that to be the case. It makes a fair amount of noise while it's brewing. The Keurig also has a greater selection of coffees, and I think you can make tea and hot-chocolate with the Keurig now.
Summary: First of all I own both a Tassimo and a Kuerig base model. I keep my kuerig at home and my Tassimo at work. I have never had an issue with either so far. The Tassimo may have a more limited selection true. But in all honesty even my big old faithful brewer usually brewed one kind of coffee. How many people really buy tons of different half pounds of coffee? You find one ya love and run with it and holidays or seasonal offerings are bought off and on.
