I'm not sure if this happened in the last WiiU update but now you can navigate most of the menus (haven't checked the Eshop yet) with the WiiMote. You can now even select a profile with just the WiiMote. I'll have to check the Eshop to see if it is WiiMote compatible as well.
I remember having a conversation on here about this a while back and I just felt compelled to try it out recently and it worked.
You can now turn on the system and start a game with no need for a gamepad.
