It is a big misunderstanding. The tablet doesn't play a traditional role in multiplayer so it's not the kind of situation where it has an inherent advantage in gameplay...rather, it presents a lateral viewpoint to the gameplay of the other users, who aren't using the tablet. (once again, i feel only disappointment as i see the need to level yet another chastisement at the writer for overstating things.) The way it is now, what with not being able to know what that means yet, is having as much a negative draw on the conversation as much as the overhyped positive outlook people saw in the wiimote before they got to actually try out the limits of its capabilities.
People think they're smarter, but they're just being dumb, in the other direction. The person at the top of the page is half right...right now, people are too unfamiliar with what's going on to even be able to make an informed decision about anything right now. As it stands, we don't even know about the actual hardware costs involved in the making of the system given how it works; speculation has been made, but it's unfair to judge by guessing too. I don't think the pricing on the controllers is entirely arbitrary.
Of course, that brings up the other issue that people have been talking about, where the necessity of such a controller comes into question when it doesn't do the same things in multiplayer as the traditional controller did back then, but on the whole, it seems to be more useful than the aforementioned Kinect when it comes to games.
tldr; just keep your damn pants on, frankly this is the kind of thing that messed up everything to begin with, just unbridled animal compulsion everywhere
