delete files, just press the trashcan while you select the files to go.
paint in photoshop, change colour by pressing it, 'while' you're actually using a graffiti spray can that is touchsensitive.
you can change all the equalizer knobs in winamp, at the same time, just by moving your fingers.

or databases, searching and moving entries, press two entries to switch places, move two different entries to two different places with both your hands/two fingers, search by pressing categories with one hand and moving the entries with the other.
