Before touch was a major major interface, Nik Software had developed an editing interface that was surprisingly good on touch devices. You essentially click a point on a photo and set the size of the area for edits to be applied to. The software will figure out regions in the photo similar to what you clicked on and then apply the edits. Creating SnapSeed on iOS really proved that the interface was perfectly suited to touch.

In Nik Software's case, it feels like the acquisition was a good balance between acquiring a team and acquiring patented technologies (http://www.google.com/search?tbo=p&tbm=pts&hl=en&...).

You can see the interface in action on their website. Load the following link (http://www.niksoftware.com/colorefexpro/usa/index.php?view=h...) and then click on "Working with control points". It's in an embedded flash player so I can't give a direct link.
