This is a great improvement, but I'm struck by two things:

1. The state of JavaScript-only application development is still nascent. The number of JS-only sites I see that are buggy, don't use PushState correctly, or have other shortcomings is growing faster than the overall trend. Not that it can't be done well, but if your JavaScript-only "app" is really just a standard website, you might want to re-think your approach.

2. There has to be a better way. There are distinct benefits to approaches in caching content and providing feedback, but JavaScript seems to be a kluge-y approach. It reminds me of frames back in the day. Some of this is browser support; some of this is lack of standardization; some is perhaps a missing piece of the HTML spec; etc.
