I feel like that second analog "stick" is a perfect encapsulation of Nintendo's present problem where their hardware isn't sufficient for the "core" but also not suitable for casuals.
Most gamers don't want a second stick. Given that most portable gamers seem to be happy with no sticks at all, the number who feel a second stick is a significant improvement represent a distinct minority. But of those who do want a second stick, what they've created will be entirely unsatisfactory. They want two built in, full analog sticks similar to the Vita, not two slide pads which are asymmetric both in position and in shape, giving a tiny nub on the right hand side. This second "analog stick" is not enough for the "core" gamers who aren't already on board, too much for the casuals who would be fine without an analog stick entirely.
