The Guardian talks with Mark Shuttleworth about the Ubuntu Edge campaign, which failed to reach its $32 million goal. "The impression we have from conversations with manufacturers is that they are open to an alternative to Android. And end-users don't seem emotionally attached to Android. There's no network effect from using Android like there was with Windows in the 1990s, where if some businesses starting using Windows then others had to follow. It's not like that on mobile. They all interoperate. Every Ubuntu device would be additive to the whole ecosystem of devices."
