Fair enough, I think the 2 spectrums of dynamo are Hippy and Commuter. Somewhere in between is 'is it going to add that much (weight, price) etc, so might as well'. I am the latter.
I do like just being able to grab my bike and always have lights running. I'd often forget to charge batteries or lights and I'd always get the fear on audaxes that my lights were not going to last so I'd run them lower than necessary.
