React isn't just 'v', but you do generally want to use something alongside it that takes care of the data. I've had a great experience using the flux pattern with Reflux.js (which is one of the 'simpler' flux implementations.) Another interesting option is Baobab.js, although that still seems to be in heavy development.

I've also used flux with Ractive.js, which in some ways is perhaps an easier introduction into the flux/react approach. Might want to check that out.

I find it hard to describe how incredibly simpler everything is now that I don't use BB anymore. With some of the stuff that 'just works' in my current setup I can't even begin to think of a clean way to do in Backbone.
