One of the things that appeals to me about angular is that you can compose your application of smaller angular apps. I think what you're talking about (and the original article) mostly are about single page javascript apps rather than angular specifically. One perk of angular is that you can use it almost exactly like knockout, as a way to get nice two way data binding, without having to go full on SPA. Unlike knockout, it also gives you a nicer enforced structure for your mini apps.

That said, I still go knockout for this sort of thing most of the time because their support for legacy browsers wins out, and in the industries I do work for old versions of IE are sadly common.
