I think it's very interesting but personally I'm not sure what bike I'd have it on, as I'm generally a fan of drops or bar ends - I like having my wrists at those angles and it feels more natural to me (I even do push-ups this way).

Too bulky/heavy for my road bike for which I like the drops enough on (but I agree that when riding more upright I don't always like the narrower grip).

I also wouldn't put something so exotic/expensive on my commuter/beater which I have to lock up. The extra 3 lbs or so probably wouldn't be worth it over the relatively short length of my commute, as my commuter is heavy enough already...

Maybe if I was a tourer/randonneur I'd consider it though. Weight/bulk wouldn't matter, but comfort would. The extra damping on the wrists/arms would be nice and being able to adjust on the fly would be handy when you're riding so many hours in the day.
