Personally, I prefer to have the real article due to accuracy, controllers, stability etc. Obviously I love to mess around with this sort of stuff but it's more of a proof of concept thing rather than affordability.Is it not better to have a PC that can emulate multiple consoles then just having one console or lots of consoles taking space.
Sorry for those that can't afford a WiiU but I reckon the cost of a PC that runs this as well as Nintendos machine (which may never happen) is well out of your reach also.
