Looks like these things are approximately 3 times as powerful as a 580II (180 w/s vs 60 w/s). Given that the 580s or 680s are supremely flexible in terms of features and trigger options, the only thing I see in this thing's favor is the power. If you find yourself short on power with the 580s, these should make a very nice alternative without opting for a monolight.
Right now I'm rocking 580s with the Yongnuo 622C triggers for full ETTL/HSS, along with full adjustments from the camera's built in flash menu. I don't see these lights replacing that setup, but they would be a great option to have in the bag for when you really need more power.
More power is a great feature (however they are not three times more powerful than a 580) but that is not the best feature. Having a tremendous battery reserve, HSS, open bulb design and the ability to use either the Cheetah radio trigger or any other radio trigger is a huge advantage.
I thought I read somewhere these lights are approximately 180w/s, but it looks like I was mistaken. The website claims 153w/s. Regular 580s are right at 60 w/s.
Edit: And now that I think about it, I can see the lack of a zooming head as being a big disadvantage. With a 28mm reflector, oftentimes a LOT of light gets wasted if you are a large distance away from your subject. With a speedlite you can zoom in to ~100mm or so and get much more efficient use of the power you have.
I see to remember a similar issue back when I used an Alien Bee B400 (160w/s) for on-location portraits. Good power, but with the standard reflector (90 degree), the spread was too large much of the time and a lot of light got wasted. With a B1600 I never lacked power, but I was stuck carrying around a really heavy monolight all day long.
