I think the Wii was cool, and was the thing everyone had to have.
Then Apple struck gold with the ipod and then iphone
Both now I think the coolness and the "must have" mentality for consumers has passed.
Consumers are looking at the value of Apple products and competition and seeing that it is expensive hardware that doesn't do a lot more than other products. It is over priced for what it offers compared to competition. That is exactly what Nintendo is offering today with the Wii U. People pay more for less when it is the must have thing that is just the way it works keep up with the Joneses. Why do people pay more for a car when they can get just as good a car from another company, because it looks cool or people think it makes them look cool.
What Nintendo is dealing with is consumers that don't need the Wii U to have the next cool thing as it just simply has not taken that line. No hype but just reality and the reality is that the new system just doesn't have a lot of things people want in a console FOR THE PRICE. If people spend more time streaming videos and using apps than playing games on the XBOX 360 that tells you what the general public, not GAF, want in a home video console. And this is exactly what MS has been going for the box that people use in their living room
If the Wii U was less 100 to 200 dollars then everything would be different. Apple isn't going to sell their next iphone for less than the competition just to move sales. The different between Apple products and Nintendo's is that Apple has a huge profit margin, highest profit margins among most all consumer products and Nintendo does not. That is why Apple is fine and Nintendo is not.
