Since some of the gamers here seem to always remember others that their Wii U is collecting dust, I am going to tell you: mine as well. But, surely for a different reason: the fan on the Wii U is pulling all the dust inside the console.
Here is a list of the applications and game's played time. Wii application includes Wii games, Virtual Console and WiiWare since PSN+ and XBOXLIVE will be taken into account for the XBOX ONE and PS4 at launch. Even if you don't like the way these services are implemented on the Wii U, they are still in there. You do not need a Wii to use them.

Got the Wii U at launch. All games completed in 85% or more (collecting items, achievements, etc), Except Assassins Creed and Call Of Duty (didn't like them that much).
I still need to play Pandora's Tower and finsih Lego City Undercover before I get Splinter Cell: Blacklist, Pikmin 3, and others. I consider myself an intermediate gamer since I have been a Nintendo only gamer since the NES. I respect other consoles (not including the Xbone with its DRM) and gamers, it is just that I realized that it is enough for me to have one console. I do not need to expend money on all three consoles since nobody is paying me to live from playing games. The time I spent playing games is enough for the life I have, a family life.
Keep playing for your fun gamers, not for the fun of others.
