Great HTML5 experience on iDevices with Sproutcore Touch http://bit.ly/aQB4Ih Fast Javascript interpreter. Who needs Flash? (ducking!)
Javascript is what drives a lot of web interactivity outside Flash. Shadowbox image or movie displays, slide shows, etc. It also powers interfaces like Apple’s .me rendition of an image browser like iPhoto.
Sproutcore is the Javascript engine inside Webkit, which is the html renderer for Safari, Chrome, Mobile Safari, Firefox and a whole bunch other browsers.
Since all of our views provide touch support automatically, this means that you can actually use SproutCore Touch to build apps that run both on the iPad and desktop computers.  In fact, we’ve found that usually its easier to build our apps for the iPad first and then desktop next – since things usually just work when you transition.
