We're still using it for our stuff (via our @beanbag/spina TypeScript wrapper for Backbone that has a few additional niceties), and I feel the same way. We can be as close to the DOM as we need (or let something manage it for our view for us), we can be smart about where data lives and how things interact with it/listen for changes, and we get a decent little object model that doesn't dictate how we think about everything.
Very happy still with the Backbone way of building webapps.
