Anyone who's interested in HTML5 should give this a look. Ares heavily leverages things like the <canvas> tag to provide a rather nice development environment.<p>More importantly it's a web app, so your tools are always up-to-date. The moment that Palm releases a new SDK or device, it'll be available via Ares.<p>I've been playing with it during the Alpha period, and I've been <i>really</i> impressed by the speed of development. New functionality and bugfixes have been pushed regularly, and the Palm developers have been extremely responsive to bug reports and feature requests. They've been iterating incredibly rapidly, which bodes well for the future.
