As for everything else, it seems like you agree with me.
No I think everybody who is biased are all the same. They all ignore facts and hype this shit out of there preferred console. But then they point out flaws in apposing consoles. I dont think that it is exclusive to the WiiU/Vita. It's the way all fans are that only like one console.
As far as the arguments the way i look at is software sells hardware. Neiter vita or WiiU has that right now so they will continue to fail until they both bring out software. I dont think either one will be as successful as there predecessor but they will do fine in the long run (just a prediction). The vita has a chance of having a very long life and Nintendo games sell well so in the end I think both will do average
