Also to it's gameplay mechanics it's meant to be a hub for your living room, as you can use it as a remote control for your tv via the infrared sensor.
I have no doubt the wii u gamepad can be used for ffxiv in your home, but I see more value on the ps vita side while in your home and on the road, same applies with other mobile devices.
