The issues surrounding the harddrive are moot. Its not the point. The point is that this follows Nintendo's pattern of providing basic services at more than basic pricing.
I'm not saying they can't make money off their products and services. Its just if they can introduce something that is simple at a price that doesn't imply simplicity, while keeping their profit margin at 30% instead of 25%, they'll do it. If it succeeds, they'll say the public didn't need the extra features. If it fails they'll say the public doesn't need any of it.
This wifi adapter is fine and dandy, especially for mom and dad who has never stepped in a Staples (or japanese counterpart), but at that price, it should be like in the $25 - $30 range.
Whatever cause even if there is a 10GB harddrive for $100, you can bet I'll be one of those idiots in line for it on release day, just like the broadband adapter on the GameCube.
