It is easy to use, I like that it requires no server side code or anything other than javascript for my client side projects. Sometimes it can take awhile when loading images via CSS background image styles so if you're looking into this maybe try caching your assets locally first? This lets me have more control over how things load on each page by not having to wait 10 seconds while my network catches up with all of the requests. We are using it heavily in our new website as well as an internal application we've been developing here at work.
