What is jQuery Mobile?
jQuery Mobile is built upon jQuery and is designed with mobile phones in mind. This can be seen in the themes available to it where page elements (buttons, input boxes, check-boxes, etc) are bigger than usual and generally have a much slicker interface than their usual web based counter parts.
One of the main strengths of jQuery mobile its its cross browser compatibility, as with jQuery cross browser compatibility is central to idea. The main task of these libraries is to make development much quicker (and therefore cheaper!) by utilizing jQuery Mobile you are provided with a well tested, device independent application that can be ran on any device, computer or phone.
How About Aesthetics?
jQuery Mobile comes shipped with a slick looking user interface similar to a top selling smart phone. The default theme is pretty impressive but this can be modified easily and eventually with the jQuery theme roller. As you can see (left) the default theme pretty nice, you click the image to make it bigger. (Thanks for the image Filament Group!)
How Can It Help Me?
jQuery Mobile can make your website accessible on mobile devices without much extra work. You can get a slick looking interface for your application that works on all the major devices without having to fork out for an iPhone app, an Android app or a Blackberry app. With jQuery Mobile you only need to create your site once.
