I've read reports that if you don't filter coffee through paper it can raise cholesterol. As a person with high numbers I've been using Hamilton Beech's Scoop to get a Keurig functionality from regular coffee.
Interesting that cafestol has also show anticarcinogenic and neuroprotective traits, so this may be one of those things where recommendations continually change over the years as groups study different effects.
I use a French press, then pour it through a filter into a liter thermos. Best of both worlds!
I've used Keurigs at work and I don't see the point. The coffee comes out weak and bland, to my tongue anyway, it's a waste of plastic, and it's a lot slower than pouring a cup from a glass pitcher on an old fashioned drip brewing machine. People at the office have to stand in line, or else come back later. Also, the Keurigs I've used offer exactly 3 sizes: small (strong), medium (diluted), and large (more diluted).
Now as to Keurig's right to proprietary supplies, this sounds counter productive. Surely they will be better off encouraging the adoption of their standards, like Adobe's PDF?
