How are they for drag when you're not using the light?
My only misgiving is: Which bike to put it on?

As mentioned, a city bike, I don't think a dynamo hub would be a practical choice for a racing bike or mountain bike, nor fit all riders.
The drag is not an issue for a bike that I use to commute to work and go shopping, the convenience out weights by far the drag, and if the worry was weight and drag there are other parts that contribute much more like the carry bags, pannier rack, mudguards that again, are convenient.
Another positive factor not mentioned would be environmental, no need to create waste with batteries.
I would imagine it's minimal. I'll never forget a demo I played with at a Science museum as a kid. A dynamo with a crank you can turn, and set of switches that allow you to turn on one, two, or three incandescent bulbs. The crank turns freely without load, and is increasingly more difficult to turn as load is added.
