I agree with what your saying but the best emulation doesn't even compare to using the original hardware.How is that a stupid question?
I'd recommend building your own pc. Great PC Games + very good Wii U emulation in the near future (seeing as how progress is going).
Wii U is about 250 here, with 200 you can buy an amd 480 graphics card,which means high settings 1080p gaming.
Excellent gaming PCs are becoming extremely cheap. And buying a Wii U a few months before its death is nonsense IMO.
