Not everyone on public boards is a young male fan-person, even if they are obviously populated mostly by people with a lot of time on their hands.
Nintendo choices seem very rational to me. This generation they make a small, cool, inexpensive device, that gives the option of an entirely new, and arguably more intuitive, control scheme.
So far, it's all wins, and the only thing we know for sure that they have given up to achieve this is image quality for owners of HD displays. Seems like a very small sacrifice given the benefits.
Nintendo can't subsidize a flop with selling OS+Office, they have no in-house production capabilities like Sony, so if they tried to trump their competitors on technical specs the result would have been a more expensive console than either the PS3 or the 360. That would have been risky in and of itself, and at the end of the day, you would have to ask yourself what the point could possibly be.
As it is, they will offer something unique, and at a price point that is likely to be more accessible than the other two consoles. As I said, it seems completely rational, and from a creative point of view, making the platform more accessible to the public in terms of price, control and ease of home integration can only be good.
