Material Design in Angular We've been working with the folks at +Ionic on a set of native +AngularJS UI elements and directives that implement the material design system. This is a complementary effort to the Polymer project's paper elements collection.
When I was watching the keynote I was like "ng-community will not let this stand, and let MaterialDesign be in Polymer only". It is nice to see that ng-team is rocking this. It looks amazing so far. Great job! I will definitely be using this on my next ng-project.
+Kevin Western true bit right now they don't work very well. Polymer's goal so far has been for compatibility across the browsers but not performance. On internet Explorer even version 10 they are pretty bad.
+Kevin Western on why we're implementing in Angular instead of just re-using what Polymer has... We're hoping the two approaches converge over time, but in the near term there are many Angular apps for which Polymer isn't an option (due to browser dependencies, etc). We work with the Polymer folks and are looking at ways to maximize reuse.
The worst thing about it is that it isn't backwardly compatible. The decision to go with css flexbox for layouts leaves the vast majority of desktop browsers unsupported. That's the downside of a "mobile first" strategy, it usually means ignoring IE.
