You realize, of course, that this is probably a bug and that this was not intended by Apple? You should also understand that millions of people are using Macs everyday and their data doesn't get lost, right?
Because, if not, I can supply many-many stories where I would loose data because of stupid Linux machines, lose gigs because suddenly the music software wouldn't start, although it did just yesterday. There are enough problems that stem from software not having an owner that from it "being controlled" by someone else. And then after bashing Linux, I can finish my email with a dramatic "don't".
Any system can fail, and it is never at the right time. And in my experience, proprietary systems are generally much more stable than floss, and are less likely to fail suddenly and without warning.
