When my book collection began to grow, I made the decision to store my books on an SD card, rather than on the device. Part of this was because as a member of the beta group, I knew I would be playing with the firmware and loading the device up again would be annoying.
I wouldn't be totally surprised to find that an unscheduled and unwanted sync with odd apps could wreak havoc on a well behaving device. I use Calibre for all my books, and other than the time when Calibre was screwed up, I have had no problems at all. My husband never uses anything but Kobo sync over WiFi. He has not had any problems with that either.
