I'd consider it if I lived in a hilly area. I'm a big wimp on downhills that I haven't seen before. For now I'm stuck in the flatlands, so I don't see the use. I've never had a problem braking in the wet.

Who knows, though. If TDF guys start riding disc brakes and the high-end companies start hyping them, they could become the next big thing. Could you imagine some Zero G disc brakes? I think cyclists would eat them up because we're sheep like that. Just look at the conversion from 9 to 10 speed.
