World Mixed

Mobile web apps are applications written in web languages (HTML, ECMAScript, CSS), that can run independently of the device web browser. They can use both standard browser APIs and runtime-specific APIs to access device functionality. They are quick to develop and easy to distribute and install.
Symbian supports mobile web apps through the Web Runtime (WRT) environment. WRT enables web apps to appear and behave like native Symbian applications, and to access device-specific functionality. WRT can be extended with PhoneGap JavaScript libraries, which allow developers to write truly cross-platform mobile apps.

Best part of widget and apps are as follows:

* Enables powerful programs, often interacting with server-side web services (e.g., information retrieval and search jump-off), and self-contained games
* Widgets' operations are mainly implemented using ECMAScript. The use of standard web technologies means an almost flat learning curve for existing web developers
* Web Runtime (WRT) provides extension APIs for widgets to access certain system properties and mobile environments
* Web apps based on PhoneGap can easily be repackaged to run on iPhone/iTouch, iPad, Google Android, Palm, and Blackberry
* This is a relatively new environment and is still rapidly growing.
Positive side
* Web applications appear to the user as regular Symbian applications
* There’s an almost flat learning curve for the web design/development community, which reduces the cost and time-to-market associated with developing mobile applications
* Migration between standards-based web run time platforms is relatively straightforward
* Cross platform support through Phone Gap
* No signing is required (unlike a native application)
* Robust Eclipse-based IDE

Negative side

* Not all common ECMA Script functions and HTML properties are supported in the current WRT platform
* Performance can be an issue for more complex applications

Lets move forward and interact with the world technology way it comes.
