Does my butt needs a leather saddle?

Is leather saddle really that good as some people said in the review?

The late Sheldon Brown said yes.. OK..I trust the guru, so I believe it.

BUT..does it really worth it with all the maintenance that it requires?

Will it suits everyone? I mean all type of cyclist- tourers? commuters? big small butts? etc.

Is BROOKS the only one making it right now? Why wouldn't the taiwanese make one as they have done with carbon & titanium bikes etc?
