I use iCloud, but I'm still not ready to trust all my back-up data to the "cloud." Apparently, I'm not alone.

International research firm Parks Associates (http://www.parkassociates.com) reports that 22% of U.S. broadband households currently would refuse to buy a "cloud copy" of digital media, while almost 30% would require a physical copy in addition to a cloud copy

"Roughly one-quarter of U.S. broadband households are interested in the 'cloud copy' concept, but for now, consumers in general are unwilling to pay a premium for cloud offerings, indicating a market still in its early stages," says Brett Sappington, director, Research, Parks Associates. "Many companies are experimenting with business models around the personal cloud to find the path to profitability."
