I should also point out that both drip machines and most homebrewers boil the water they use for coffee. This is a huge don't--boiling temperature is a bit too hot for coffee beans. About 195 - 200°F is the proper brewing temp (for anyone not still stuck in the Imperial System, this is approximately 91 - 93°C), but if you need it a little hotter, 205°F (96°C) is as high as you should go--any higher will disrupt the flavor. Temperature for the Aeropress is lower, at about 175°F (about 79 or 80°C). Chemex should definitely not exceed 205°F or 96°C, and yes, it does strip the oils if you use a paper filter (mesh filters exist, but they require a bit more technique to use).
