..a home office or personal type setting.
But even in a home setting bios password and disabling the floppy (if not needed) are ways around this. Heck, I'd even go as far as a bootup password as you are more likely to be at home during reboot than you would be at work.

It's little things and the way BIOSes are made today, it's as simple as removing the battery any more. Some boards don't have that option (so you better remember the password(s))
