Now, in Germany where I live, I have to keep all my business data safe for ten years and have them available for the incidental scrutiny of the tax office. You know how old papers look after a while. But they do still exist. And I'm not talking about those silly fax-papers we used a few years ago and that didn't survive one season.
Now, how reliable is online-safekeeping? Is it any better than thermo-fax-paper? Will your data be stolen faster than you can say "She Came in Through the Bathroom Window"?
So, in the course of the following years, we will see vast amounts of private data now spinning on private discs oozing out to servers we know very little about. Even now, millions of users today easily hand out all their mails to Google's GMail service, without a worry about privacy.
Then, there is the perennial issue of viruses, trojans and zombie robots threatening everything and everyone online.
