While a press is great at home, what is not so convenient is a work environment where storage and dispensing loose coffe becomes an issue. Carrying a cup and a press full of hot coffee introduces health and safety issues (opening doors, swiping keycards etc.). And then disposal of coffee grinds and cleaning a press is more complicated than a used cup.

Nothing is wrong with it.

But as we have to repeatedly point out, there is nothing that competes with the Keurig on convenience and speed. That's their advantage.

Their customers don't want a messy, time consuming French press.

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.

Any references on what is being filtered out by the paper filter that is transmitted by the mesh in a cafetiere or in a moka pot or expresso machine?

Just interested, not challenging, I'd imagine it is a particle size thing.

Supposedly Cafestol http://en.wikipedia.org/wiki/Cafestol http://www.ncbi.nlm.nih.gov/pubmed/1862798

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?

Nothing wrong with it, just less convenient.

but how will someone charge you 50c a cup for stale shitty coffee?
