A developer who built an app with PhoneGap/Cordova summarizes his experience and explains what you can reasonably expect when building mobile apps with PG/Cordova:

The biggest misunderstanding with Apache Cordova is that it does *everything* for you. But it’s not the case. It is just the base for your application. It supports you to package your app and helps you to access device features like the camera. Nothing more. There is nothing in Cordova which helps you to organize your App in terms of for example MVC. It’s not an application framework.

There is currently a big opportunity for filling the gap: A framework on top of Cordova that:

• is very lightweight so that it performs well. Can be accomplished by having only very limited browser support
• comes with a UI library that emulates the look and feel of its host operating system, primarily iOS and Android
• provides an application framework, e.g., MVC or comparable.
