The other systems OS's were missing features at launch, too, so don't claim that's a Wii U only issue. The OS was actually complete at launch here, wasn't missing anything (though it did require a patch, but so did PS4 and Xbox One. Xbox One was missing standard features like bloody data management)
Also, we have full confirmation that the account system is completely unified (apart from cross purchases).
Overpriced is subjective. Considering it's only just broke even, it's clearly not physically overpriced.
No online Nintendo games is erroneous.
Struggling with HD development is erroneous. They underestimated the change, but they didn't struggle.
Only 1 person using the controller is by design.
Technology isn't "7 years too late"
Games are innovative, more so than titles on other platforms.
I'll give you advertising, though.
