The main reason you should want to own a Wii U is because of the large amount of great games it has to offer. I know that there are a lot of people that say there are no good games, but it has tons of great games. Here is the list of the games that I own, if you want an idea of some of the games the Wii U has. I love all of these games, except for Pac-Man and the Ghostly Adventures (it's garbage).
Game & Wario
Monster Hunter 3 Ultimate
Nintendo Land
New Super Mario Bros. U
Need for Speed Most Wanted U
LEGO City Undercover
Pikmin 3
Sonic & All-Stars Racing Transformed
New Super Luigi U
The Wonderful 101
The Legend of Zelda: Wind Waker HD
Rayman Legends
Super Mario 3D World
Donkey Kong Country: Tropical Freeze
Sonic Lost World
Mario Kart 8
Scribblenauts Unlimited
Wii Fit U
The Amazing Spider-Man 2
Pac-Man and the Ghostly Adventures [1]
Ducktales Remastered
Hyrule Warriors
Super Smash Bros. Wii U
Captain Toad: Treasure Tracker
Mario Party 10
I'm also planning on adding Kirby and the Rainbow Curse to my list in the future.
It's only getting better with games like Splatoon, Xenoblade Chronicles X, and Star Fox coming in the future. Now is the perfect time to purchase a Wii U, if you don't have one already. Plus, it would be easier for you to save up for one since it's the cheapest console on the market.

If you aren't a fan of a lot of Nintendo games, though, I wouldn't really recommend it. If you love Nintendo games, you'll love the Wii U!
