Difference between jQTouch and jQuery mobile

Question

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

some good info here

http://jquerymobile.com/strategy/

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.

For detailed understanding and to know the differences between mobile frameworks,

As I discuss on my blog post:

http://zsprawl.com/iOS/2012/04/comparing-jquery-mobile-vs-jqtouch/

I find jQuery Mobile a lot more feature rich and with a lot better cross platform support. JQTouch is very lightweight and great for "form-based" apps that just need navigation. It is missing a lot of the features that users have asked for, and have been turned down, like fixed footers and tabbars.
