Here's the thinking behind the concept idea:
...why we do these concepts – to show the app can be even more beautiful and functional. We will be happy and you – our readers to take participation too – through comments you may give ideas about new features or improved ones. And will try to send the concept of the creators of the application – if they have the desire and opportunity to improve the app, or to add missing features.
Whether the ideas will be picked up or not is not the point, it's about playing with the format, it's about curating opinion, and it's about showing what the platform can do when pushed. You can contribute to the ideas over on 1800 Pocket PC.
