I'd take any console for free.
A second Wii U would be great for playing online, I have to sit on the lower firmware with no internet to use loadiine

.
I know theres firmware spoofing but I don't really want to do that.
For people who don't have a Wii U, they should take it because there are a few gems on the Wii U.
And for people who really don't like it and won't touch it, they should resell it. Its not like trying to sell an ancient computer, it will get you something.
Can't think of any reason you wouldn't take it. You could curb stomp it if you were really inclined.
