I love the convenience of a single cup coffee maker. I generally drink a regular "American" cup of coffee rather than espresso.
I am currently using a Tassimo coffee machine, and although the coffee is ok, it's not great. Since the have terminated their relationship with Starbucks and Seattle's Best, pretty much the only decent coffee they offer is Gevalia.
I am considering getting a Keurig machine which has a greater choice of coffees in their K-cups, and which also allows the user to put any coffee into a refillable cartridge...but there goes the basic advantage of these machines...convenience.
Does anyone have an opinion re Keurig vs. Tassimo?
