Had a phone talk yesterday with Scoble, about lots of things, including the Color app for the iPhone. He paid a lot of attention to it, because they raised so much money and came out the gate so strong. Then he told me what they could have done that would have stood a much better chance of working. It's a brilliant idea, one worth sharing (with his permission, and full credit).
What if they gave you a piece of software that, when you took a picture on your iPhone, the picture would automatically show up on your iPad or Android phone? That would be pretty cool? No wires, no Bluetooth, no configuration. Since you're logged in under the same name on all these devices, the only permission they would need is a preference that says "share photos with all my devices."
