Oh man, I just received a French press for my birthday a few days ago, and I LOVE it! I'm not a coffee snob at all - I can't taste the difference between fresh ground/weeks old, Starbucks/gas station, expensive/cheap, flavored/unflavored, etc. But the difference between the French press and regular old coffee maker is huge.
The only drawbacks I've found are that it's a little more labor-intensive (you can't set it up the night before and then just flip a switch in the morning) and it seems to use a lot more grounds to make the same strength of coffee. It might become a weekends-only thing once I start working.
