I don't really buy this. I see literally dozens of people a day using tablets – mostly iPads. They're reading books, playing games, watching videos, using Facebook. I think it's pretty clear what it's good for. I suspect that iPad sales have declined not as a result of the iPhone 6(+), but because the market is becoming saturated. There's little reason to upgrade past a certain point – sure, iPad 1 -> 2, and iPad 2 -> Retina were improvements. But aside from general performance improvements, there haven't been many changes since. In this situation, it's hard to see why most users would upgrade.
