To Susan on the high altitude question. The boiling point of liquids varies proportionally with pressure. Higher pressure, higher boiling point, and vice versa. Low pressure at high altitudes means the water might be boiling before it gets to the correct brew temp. I imagine they have a pressure vessel that allows pressure to build as the water heats in the coffee maker, so it won't boil before hitting temp. If you live below 4500 ft elevation or so (boiling is 203.9 F), it's not worth it.
