Ugh, break a few smart phones over the holidays and you get 'the loaner'. It's a nokia 6121 with a cracked screen and barely counts as a smart device... Having a tablet fixes a few on the go problems and keeps the pregnant wife happy :P
I'd use it to create a simple open way of combining augmented reality, panoramic photos and 3D assets (via Unity) so people can create simple animated and immersive environments on their tablets. I'd start with a recreation of the pink and white terraces so when you are on the boat trip at Lake Rotomahana you could see something like this in full 360 degrees immersive glory (note: taken on my cheap android phone). Navigation in a panorama on a touchscreen poses some interesting challenges but can - I hope - be overcome..
