Nice, I love jQuery because it made DOM manipulation a breeze by abstracting everything. But I am getting the feel that jQuery Mobile assumes "what" it is that developers are creating, making it less abstracted and more narrow minded (for instance, that we all want right to left iPod style page navigation). Or perhaps not, I could just be wrong.
jQuery Mobile is not a mobile version of jQuery - it's a UI library for mobile devices. A better comparison would be jQuery Mobile to jQuery UI. Both projects depend on jQuery proper, and both provide UI-widgets (they are absolutely "narrower" than jQuery, as you say).
