You don't sell 14 million consoles of a fisher price tablet without having some very dedicated fans.
Though the Wii U actually got me into Nintendo after I had moved away from them with the Xbox.
Did Wii U sell as much as it did because Nintendo fans buy anything or because games like Mario Kart 8, Super Smash Bros 4, Super Mario Maker & Splatoon were high quality and desirable games?
If it sold because of very dedicated fans than games like Kirby: Rainbow Curse, Animal Crossing: Amiibo Party, Paper Mario: Color Splash & Star Fox Zero should have been multimillion selling hits like the other games I listed were.
