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.
