Carbon rims. Why?

Apart from being expensive, carbon rims appear to beset with problems. Fragile, expensive special break pads, issues with wet weather braking, overheating on long descents and so on.
Whilst I can understand a top level racer wanting to gain every small advantage, for your average club/sportive rider why take on all these problems for such a marginal performance gain over the better alloy rimmed wheels?

I have never ridden with carbon rims, am I missing something? Are there advantages I am unaware off?
