If only playing Nintendo games isn't an issue for you, then I'd say Wii U would be good for you. Buuuut, if money is tight, I wouldn't be in such a rush the buy one just yet. The longer you wait, the cheaper it will be, and the library will be bigger.
Despite some downsides, I do generally enjoy my Wii U. It's a fun system that just needs a few more heavy-hitting games to strengthen its library.
