Kobo just posted this video on their blog. It looks but interesting. I'd recommend that you turn off the sound. The background music is annoying.
We had originally planned to take our existing iPhone application and ’scale it up’, but as we began to see the richness of the interface and interactions that are capable on the larger screen, we knew that wouldn’t cut it. We had to start from scratch!
We’ve taken a brand new approach to our iPad application compared to the apps you’ve seen from Kobo in the past, but still stayed true to our values. We set out to create an immersive experience by making full use of the iPad’s large screen, and by adding our own flavour to deliver a breathtaking experience. The Kobo experience on the iPad is truly unique.
