I've had my Wii U since 2013 and it's worked like a champ since then. It's always been hooked up and ready to go and never neglected for more than a month or so. I'm not afraid of the NAND corruption because for one, I think the issue is overblown, and secondly, it seems only a certain type of NAND chip is being affected, and my 8GB console doesn't have it. The Wii U is by far my biggest collection as I own 120+ discs and 72 digital titles.
