I, OTOH, have all my contacts on paper...(and I'd be smug about it except I don't have hundreds, just dozens, which is quite managable). There _was_ something about a 'hole in security of cloud computing' in a recent MIT Tech update (but I only get the headlines, not the full story, and doubt I'd understand without some major studying, which I just don't have time for at this point...).

RE: Cloud Computing Smears (Was: Google Wave)
Er. In that sort of a situation, I myself would set up a RAID for storing the data, *much* less chance for losing it. I'd just do that anyway. In fact, the computer that's still in a box and is destined to replace the one I'm using right now has a RAID, because I seem to have a knack for catastrophically losing hard drives that baffles my husband entirely. (He has more problems with his PDAs than I do, so I guess there's *some* sort of balance) I think I've lost 2 or 3 in the past 6 years, and any data that wasn't backed up, which is kind of rough for an information junkie. For *that* sort of application, I'd go with a decent number of disks in the array for any one set of data. My own problem with cloud computing is, if the magical set of wires between me and my data has a glitch, I can't get to my data, and we end up with Grumpy Julia, which is not pleasant for anyone directly involved. (Jo Anne -- a RAID is a Redundant Array of Independent Disks, where the data is stored on multiple disks and checked for accuracy on some regular basis. If one drive goes down, either the data should be duplicated somewhere, or there should be enough information stored on another disk or disks to reconstruct what was lost.
