If so, its important to keep in mind that Polymer is in a "developer preview" state, and we have not declared it production ready yet.
If you need to ship, then use whatever you feel the most comfortable with. Fewer cognitive barriers and less stress.
However, if you've got the time to play around and learn how web components work, then hop aboard!
There's an introduction tutorial here: http://www.polymer-project.org/docs/start/tutorial/intro.htm...
The calculator demo is pretty simple: http://www.polymer-project.org/components/paper-calculator/d... (source: https://github.com/polymer/paper-calculator)
Salesforce has a nice polymer-based web component set for building mobile apps that integrate with the Salesforce apis: https://github.com/ForceDotComLabs/mobile-ui-elements/
And the demo app at I/O is here: http://www.polymer-project.org/apps/topeka/ (source: https://github.com/polymer/topeka/ and https://github.com/polymer/topeka-elements)
I hope you'll find some useful web components in the future that you can just drop in to whatever project you're working on and save some time!
