My Wii U never takes that long to update, the first update when i got the Wii U did take some time but game updates never take long at all. As far as your choice of games, NSMBU is a fine game for people who haven't put alot of time into the other entries in the series but for people who have it would seem to be quite comparable to the others and might would turn you off in some ways. Then you choose a Mario and Sonic game which has always been pretty average at best series, you really need to play the gems on the Wii U.
Super Mario 3D World
Pikmin 3
Legend of Zelda WWHD
Deus Ex: Human Revolution
Rayman Legends
Wonderful 101
Play those then judge the console, the Wii U has its faults but it also has some pretty great games as well :D
