The Wii U titles appear to be far more integrated into the OS. On the Wii it appears that games were run at a pretty low level [0]. Also, on the Wii, although there is an updatable system menu capable of downloading and running some small apps, the menu shown when you press the home button while in a game was included with each game as part of the SDK, not as part of the OS [1]. (The Korean version of Mario Kart Wii was found to have unused files for a Chinese home menu [2].) Meanwhile on the Wii U it is possible to launch an entire web browser and certain other apps from the home menu and still return to your running game afterwards.
