We’ve had cloud-based services for consumers for years. That includes online storage services, photo sites like Picasa and Flickr, social networks like Facebook and Twitter, Web apps like Google Apps and even online email systems.

Amazon’s a well-known brand name that engenders a high amount of trust.
