Exactly. It can certainly excel in a niche, as Apple is well known for doing. I think that niche exists, but I think it's shining point will be enabling new ways of doing things we never thought of, primarily through it being a standardized platform with creative eager developers.

I don't think there's any reason why a nice simple product with great design and UI can't be used by all, including the technical/geeky type.

I don't think it's going to replace traditional computers.
