The DS, with it's rather funky touch-screen, is to get an update of Pac-man, titled Pac and Roll.

In "Pac'N Roll," the inhabitants of Pac-World have been turned into spheres by the evil monster Golvis' Ghost Light. Pac-Man must roll his way through Ghost-Land, collecting pellets and confronting Ghosts to save his family and restore peace to Pac-Land. Introducing an innovative new control scheme, "Pac'N Roll" lets players control Pac-Man with the Nintendo DS stylus. Players can roll and dash around the environment as well as execute maneuvers such as hairpin turns, immediate stops and precision rolling with effortless strokes of the stylus.
I'm in the midst of reviewing a DS and I've got to say, that in some games the touch-screen is superb... anyone who owns a DS will have the demo version of Metroid Prime Hunters which makes full and excellent use of the touch screen.
