Is the Wii U a failure in concept or execution?

Both!

Execution: Horrible advertising, lack of effort in courting 3rd party titles when it mattered most (Q1/2 and GTA5)

Concept: Gamepad is too costly and not a strong enough gimmick. Alternatively they should have upped the Wii U's power so it was at least comparable to the PS4/X1 and just went for the premium price tag. $399.

oh god, why?

Why what?
