Not to be a dick, but that really sounds like a music-snob response. Yes, if you know your chords it's not really useful, if that's all you do. But some people (and I admit this is a scary thought) only know about 4 chords and to change the key of a song, must use a capo. That's the extreme end of the spectrum.
The reason I think most people, including myself, use a capo is for the tone you get from your guitar. Need proof? Take Here Comes The Sun. The lick in and of itself is fairly easy, nothing too special. But if Harrison had played the song without a capo, the tone produced from his guitar would have been lower, losing that bright, cheery edge to the tune that makes it such an uplifting tune. Another example would be a number of Simon and Garfunkel songs (Bookends comes to mind).
So capos do serve their rightful purpose.
