Difference between jQTouch and jQuery mobile

Solution 1:

jQtouch is optimized for WebKit, jQuery Mobile is looking to support all mobile devices; that is my understanding

Solution 2:

Additionally to Aaron's answer this is what I've come up with so far:

• jQuery Mobile is an offical and generally more active jQuery project (alpha 4.1 - April 7, 2011) whereas jQTouch, created in 2009 by David Kaneda, has been relatively quiet until release of beta 3 (May 3, 2011)
• jQTouch is a jQuery plugin (see "Staying on jQuery" section) while jQuery mobile is presented as a framework
• jQTouch is focused on small screen device, from their blog :

Apps developed with jQTouch will certainly run fine on iPads and other tablet devices, but we aren’t going to automagically convert to a more tablet-friendly UI that takes advantage of the additional real estate. If you are in need of a JavaScript library that magically updates your UI for everything from small screens, to tablets, to desktops, check out Sencha Touch.

• I realized that the guy behind jQTouch also worked/works on Sencha Touch, which got me even more confused. But he gave some details about the difference between these two on his blog.
