You're missing the part about how single-page, client-side apps are much more performant _once_ the page loads. Spike is trying to get the best of both worlds (hence "Holy Grail").

Server-side gives you fast page load times. Client-side gives you fast user interaction times.

That was the straw man I was thinking I saw in the post.

Why not use rails to load the page (no BYO framework involved) and then use javascript/backbone/etc on the client-side; as opposed to bringing the client-side technologies server-side to accomplish the same thing?

I'm thinking specifically of the search page example that was represented as a screenshot in this blog.

Exactly.
