I think we need to update our docs examples to show the different md-button options. They still show <md-button>, even though you can use the class directly on a native element. I want to believe people won't try to put an href on <button class="md-button">, but I'm not convinced. Anchor vs. button affects how people will interact with keyboards and screen readers, so it's important to make the distinction.

Updated Plunkr showing an anchor tag with href: http://plnkr.co/edit/np1n4JicBQEc2EuAgDQj
