Personally, I've had more data loss with FreeBSD. My experience does seem to be unusual, but FreeBSD is no panacea, and no substitute for backups. On the other hand, Linux emulation mode works amazingly well; you don't actually have to give up user programs. I do miss "supermount", but I use vmware and the Linux version of Netscape--which works better under FreeBSD than under Linux. You really don't have to give up much even for a desktop.
