Microsoft may have hoped their Windows Marketplace for Mobile would dominate app store news today, but Palm are having none of it. The company has just launched paid software in the webOS App Catalog, together with adding a few more free titles, with a fresh injection of almost thirty new apps. Meanwhile, they're also broadening their appeal to the open-source community. In a developer event late yesterday, Palm revealed that it would be enabling developers to release their applications via the web, rather than solely through the App Catalog; Palm will provide a link for downloaders for each new title submitted in this way, but not run the apps through checks as it does for the existing download store. Meanwhile they've also confirmed that they'll be waiving the regular $99 annual fee for webOS developers if the software they're producing is open-source.
