The introduction of the iCloud made me re-think a product idea I had before.
I once thought that it would be cool to have a product like the eye-fi that will send a photo from your high-quality camera to the iPhone, iPad or Android device for quick editing (instagram style) before sharing. Eye-fi has an mobile app that can do something like that however I don’t own a card so I never tested it.
Now, with the iCloud, if you had a (lets call it) iCard, you could turn every digital camera to an iCloud enabled device with seamless iOS devices (and OSX) integration.
