![What is webOS?
Palm© webOS™ is Palm's next generation operating
system. Designed around an incredibly fast and
beautiful user experience and optimized for the
multi-tasking user, webOS integrates the power of a
window-based operating system with the simplicity
of a browser. Applications are built using standard
web technologies and languages, but have access to
device-based services and data. [1]](https://image.slidesharecdn.com/webos-sortingthoughts12-2009-091211085020-phpapp02/85/webOS-App-by-Example-Sorting-Thoughts-3-320.jpg)
![Application Model
„The webOS application model combines the ease of development
and maintenance of a web application with the deep integration
available to native applications, significantly advancing the mobile
user experience while keeping application develop- ment simple.“ [1]](https://image.slidesharecdn.com/webos-sortingthoughts12-2009-091211085020-phpapp02/85/webOS-App-by-Example-Sorting-Thoughts-4-320.jpg)

![Conclusion
webOS make it pretty simple to build an app
but the apps are also simple - maybe too simple?
JavaScript is not Java™
SDK is okay but Ares[4] make it much simpler
App Catalog is currently a little bit confuse
