Just get a cheap ass Wii:
There's not a single WiiU game that's even in the same league as the ones you have for the original Wii currently. There will not be a decent amount of WiiU games until the end of 2015 (or even 2016) either, while the Wii had tons of
hidden gems that can hold you over until then, if you really are in the mood for something different. Paying the extra money for WiiU hardware isn't worth it currently. The fact that people try to hype it up with literal shovelware like Zelda Warriors from Koei, the umpteenth New Mario Map Pack (which has the only worthwhile iteration on the original Wii anyway), titles that are still at least 2 years away (including Zelda, don't believe anyone gullible enough saying this will be out soon lol), or titles that have high risks of not even coming out here (Fatal Frame), is pretty telling of how desperate the situation on WiiU is. Also, most of the 200-300 bucks for the console go to the controller, which is pretty worthless all around. Outside of minigame shlock, there's maybe one or two titles at best that benefit from it and for the most part, it actually cripples the console (Currently, I can't even enter the system settings, because my charger is broken and even that one is unique and can only be repaired by Nintendo and not be bought). I mean, if Off TV is really your thing, you might as well get a 3DS. Just like the original Wii, it covers most of the experiences you can get on the WiiU, but offers many more - including actual 3rd party support.
Even the online store in Wii U is shit and you won't miss out anything if you only get a cheap Wii (just not the Wii Mini, which doesn't have online features). The choice of classic platforms and games has become truly huge on the original Virtual Console, meanwhile the one on Wii U is currently tracking to not even have a fraction of it even in it's whole lifetime.
Also, not being a Nintendo gamer, does that mean you never had a gamecube? Because the original Wii can still play that one too, while the Wii U can't. GCN also had several of the best games of it's generation and again, tons of hidden gems - while Wii U just had a 2 year long drought and again, isn't gonna be worth it until it has more games accumulated at the end of 2016 or something. I have always been gaming primarely on Nintendo platforms, but I unfortunately can't deny that the WiiU is quite a trashy product and if you aren't a Nintendo fan to begin with, or you wanna get into their libraries, this would be by far the worst choice you can make.
