best advice I have heard from CNN
data that you consider important should be backed up regardless of where you store the data. YMMV but I consider my contacts (among other data) important. BB's are very reliable in my experience but that doesn't mean that a hardware failure can't occur. Nor does it mean that you won't lose or break your BB.

BES wireless sync (and backup) also works really well.
