Some of my favorite desktop apps are open source or web based. GIMP, Pidgin, x-chat all get used on a daily basis.  Why should we settle for all these different proprietary SDK models that require us to have a certain operating system to develop on.  These last couple weeks I’ve explored getting started with the iPhone SDK, and the .NET SDK for developing for Windows Mobile.  Honestly . . . Apple and Microsoft have missed the bus.

I feel like I’m beating a dead horse with this java thing, but HTML and JavaScript are well established programming standards.  The fine folks over at PhoneGap have put together another tool using HTML and Java to develop apps not just for the iPhone, but for the Android, Blackberry, and most definitely coming soon Pre.

J2ME Polish is a toolkit that allows you to “develop, design, and build your applications on the platform of your choice: Windows, Mac OSX, Linux or any other Java enabled operating system”

This one caught me off guard a bit because you can 1: program in Java, and port your app to Blackberry, Palm, DoJa and WIPI devices.  Not only that but Winmo, iPhone and Android platforms are natively supported.
