What's stopped me so far: the setup is more expensive than the Cree LED lights that work great for me, I take the lights off for half the year on one bike at least, and I begrudge even 4-6 watts. And as far as I know, they still aren't as bright as the battery lights. But still, on the commuter workhorse it's a tempting choice.
Yes I researched them, dynamos in the hub, very clever. I won't get one either as I don't do night rides often enough to warrant but want a great boon for the commuter and traveler. You would want to spend the big bucks and get the one with minimal drag in daylight hours though. I'll keep an eye of this for the future.
