Striving for uniqueness and innovation is a high risk high reward strategy. Nintendo have seen both success and failure in that regard. The Wii was a storming success, nothing less. The reasons given in the OP for it being a failure are 100% opinion.
The unique aspect was only one of many reasons why the Wii U hasn't done well. The Wii's uniqueness has not 'cost' Nintendo. The only blame that could possibly be pinned on the Wii for the Wii U not doing well is that it would always have been a hard act to follow.
