I've been working on my first AngularJS project since October. It has some strangeness, but on the whole I am impressed.
Easy, fast iteration powered by Node.js.
Directives hint at what HTML should have been from the start.
Simple module system for easy code isolation.
Limited by HTML, JS, CSS, W3C; and not my imagination.
jQuery experience doesn't really help much.
Directives fall short of next-generation HTML/JS features such as custom elements et cetera. Check out Google's Polymer project for a taste.
Module system seems overly complex with factories, services, values, constants, controllers, directives, filters. Plus everything lives in a single app namespace, so not much win over single window namespace.
Please note these may be resolved by the time you read this post.
I opened an issue to allow ngTransclude to operate more like <content /> and <content select="..." />.
Directives are a big part of most Angular apps, but directive documentation is at http://docs.angularjs.org/api/ng.$compile.
