From my very superficial reading of the article it would seem like the win is that you're getting huge amounts of density. I think their argument is that a typical web-style datacenter is throwing up hundreds and hundreds of commodity servers to do some sort of distributed processing tasks (think of something like a hadoop cluster or a ton of app servers behind a load balancer). With this setup their argument may be you're no longer in need of a giant network/switching infrastructure to do these types of compute tasks. Plus all the power/cost savings of only needing a couple boxes just to get those thousands of CPUs. I wonder what kind of RAM these things are going to have, as obviously that's pretty crucial. But yeah, losing one of these things would cause more than a little headache of an outage. Seems like an interesting approach that's worth more thought though.
