The big reason: Cross platform compatibility. Not just between mobile platforms, but even between mobile devices and webservers. Our devices are so powerful now that you can run a full blown webserver on it if you choose your DB system wisely. That's why we use CouchDB - replace it with CBL on mobile and take your whole webapp with you for offline use. I'm Swiss - we have lots of tunnels ;-).
