Below are three screenshots from Google Currents on the iPhone (Google's Flipboard-like product). Rather than commenting specifically on the Currents product, I wanted to share three themes I was reminded of when first using the app: 1. Mobile UI is really critical and really unique. (you've heard this before and will again & again).
2. Mobile UI is very different on iPhone vs. iPad. Different real estate and different behaviors / expectations. The below examples demonstrate why this experience just does not work on iPhone. You have to treat them differently and create unique experiences specifically tailored for each.
3A. The genius of Flipboard is not the content. That's become more of a commodity: publishers of course want their content in as many places as possible. It is the UI and the interaction. It is the magic users feel when opening, using and sharing.
3B. And it's that magic that you need to capture within your product(s) and experience(s) - of course in your own, relevant way.
