I love that it's easy to use, can be used for any website/app regardless of size or complexity. It is quick to learn how to build an app with wurfjs since there are plenty of examples out there. There isn't anything particularly negative about this piece but if you want something that works well without much effort then give it a go! I am solving problems in my day job by creating apps using AngularJS which requires me to spend time learning new frameworks every few months. This saves so many hours as all our mobile web applications now have native look and feel - no more html5 boilerplate templates required anymore! We also noticed improvement from speed issues previously when working with angular 1.x before moving onto 2.0+. The best thing though was we were able to create cross platform (Android & iOS) solutions quickly and easily.
