There are number of javascript frameworks out there to bring touch events to smart phones and tablets.
I am particularly interested of jQuery announcing their own because 1. The project I am working on uses jQuery and 2. jQuery has been my favorite JS framework.

I’ve tried Sencha, jQtouch, and others but I wasn’t happy with any of them. I will give jQuery Mobile a try and share the result with you shortly.
