Word's thesaurus is adequate for the mental lapse. "Damn it, what's that word, you know, for that thing (or idea or color or whatever)?" but not much use beyond that.
I'm become a bit of a thesaurus elitist. No online or paperbound thesaurus seems adequate once you've had use of the big hardcover sucker sorted by concept, with so many somewhat-related ones listed that it's a godsend.
But Word's abbreviated one? Meh. Good for brain farts.
