Before I get flamed by both road riders and MTB riders, let me say that riding "out of your element" is obviously possible - it just isn't optimal.
With my hybrid, I could road ride, commute, and explore any trail I got the notion to. My current touring bike is closer to a hybrid than either of the "special purpose" road or MTB styles. Yes, I give up the ultimate efficiency, but that's why I like to keep more than one bike!
