The two biggest concerns about cloud storage are reliability and security. Clients aren't likely to entrust their data to another company without a guarantee that they'll be able to access their information whenever they want and no one else will be able to get at it.
Apple co-founder Steve Wozniak spoke about his concerns regarding the cloud after a special performance of Mike Daisey's monologue.
Wozniak revealed that he thinks the cloud is going to be "horrendous,".
"I really worry about everything going into the cloud," said Wozniak. "I think it's going to be horrendous. I think there are going to be a lot of horrible problems in the next five years."
"With the cloud, you don't own anything. You already signed it away," Wozniak continued. "The more we transfer everything onto the web, onto the cloud, the less we're going to have control over it."
After last night's performance of a revised version of the monologue, Wozniak said: "We know we (citizens and consumers) have a voice. We can speak (about labour condition), but we can't act like, oh, Foxconn is bad or Apple is bad."
To that, Daisey responded: "I hear what you're saying about the fact that everyone goes through evolution, but its not as if the evolution was natural in the sense that we are the ones who brought the jobs there."
Wozniak has spoken about his cloud concerns previously, during a Q&A session with fans in July. "We don't own anything on the cloud," he said. "We've probably signed away any rights. It's a move toward licensing (great for monopolies) instead of you buying and owning stuff. Since you don't own it, it can disappear or change with no warning."
