This whole "let's move everything to the cloud" movement seems primarily to be driven by people who don't have a lot of work to do on computers besides browse websites, email, and write blog posts. They may do a lot of other work, but their computer use is fairly limited to a few tasks.
Meanwhile, business users are only going to make the jump when the multi-billion dollar companies that employ them feel comfortable having confidential information stored on a server in some other random country (i.e. probably not in my lifetime).
That's the problem Google and the other "cloud" providers have to overcome before they can claim victory - not some minimal use case like this.
