Well, it's too early to say with any certainty how Switch will be received by the mass market, but (a) Wii U only supported off-TV play with a limited portion of its library and within a very limited physical radius, and (b) "the same gaming experience at home or on the go" is the singular, clearly defined USP, at least in the marketing up to this point (hopefully the presentation doesn't muddle the messaging with too much focus on motion controls or touch). There was no easy way to explain what the point of the Game Pad was in a single sentence, which is almost invariably a recipe for failure.
