A couple of days ago Corel has launched Digital Studio 2010: a software for both video making (also DVD burning) and for photo retouch and organizing. The new version offers touch operation.
That means that with, of course, a dedicated device it leverages the Windows Touch feature available with latest Microsoft® Windows® 7 and allow touch based operations like photo organizing.
The product is available for download at a retail price of about 100 $. Link to US Corel website: http://www.corel.com/us/
