Looking at the source code of the example projects, it seems that Sencha Touch continues to use HTML/JS/CSS as a development environment for native apps, not to be used on the web in any other way than as mobile apps. For instance, a search engine cannot read any content presented by a Sencha app, unlike a jQuery Mobile app. To me, this makes their description of Sencha Touch 2.0 as an HTML5 framework disingenuous. All attacks that have been made against Flash for compromising the accessibility of content for a slick user interface can be levied against Sencha Touch. Can this be avoided?
