How the WiiU gamepad should have looked.
Then people who already had a new3ds would have been able to buy a cheaper console-only wiiu, and people who didnt, would be able to get a home console AND handheld in one purchase, they could then have made it so 3DS could be played on TV, or WiiU on 3DS with the ability to do off-screen play and show the main screen at the top and the normal "off screen" window left interactable at the bottom.
Then they could have done cross-buy so people could buy a wiiu game and get the 3ds version as a digital download / have the 3ds install data on disk so no download was needed beyond authentication, and allowed cross-platform progression and save data.
Would have been MILES better.
