There are number of reasons outside of just submitting to use a <form> tag in your code. For one, angular wires up validation results right into the form object. If you didn't have the form, you wouldn't get that functionality.

Similar to the validation properties that exist, there is also a form.$submitted property that will be updated to true when the form is submitted with an ng-submit. This will not happen on an ng-click.
