WebOS developer site: http://developer.palm.com/index.php http://developer.palm.com/index.php Palm apps are "cards" that consist of html/css/javascript. All programming is done in Javascript. WebOS apps use the Prototype javascript framework, and you make calls to Palm's Mojo API to instantiate your app's widgets, push between screens (scenes), and access the device's services (location, storage, calendar, telephony, orientation, etc) They offer a free SDK which comes with a Palm Pre emulator which runs in Virtual Box, and there are a handful of sample apps available. I've been working with it for a few months and I can say that while it's not as easy to use as other more widely used programming environments, they give you enough to get started and build some simple apps. It can be frustrating at times, but I think this is mostly because of how new the programming environment is. If you want to learn Python or Rails, there are books, screencasts, examples, blogs, etc. If you want to learn WebOS, well... there's a developer forum and a smattering of beta documentation - good luck!
