Now, now. Be nice. :-)
You're both right, though, in that this is a kick-ass hacker project, and also not a particularly efficient way to get supercomputing power because you *must* have hackers to run it, and hackers are rare and expensive, except when they're free, and then they're even more rare.
So, it's a cool hack. It's not really much of a way for a production environment to get supercomputing power. Can you even imagine how finicky 133 old intel-based boxes must be? Yipes. So, I'd propose a corrollary to their price/perfomance comparison-- as price goes to zero, admin cost goes to infinity (i.e. you can't pay people to admin something like this. They'll do it cause they love the idea or not at all).
Not the real rusty
