DACLs. Windows-only folk make a big deal out of these, saying that the UID/GID-based security of UNIX filesystems is inadequate, and that you need NTFS (which, for all that it's attached to a steaming pile of shit operating system, is actually a pretty good filesystem).
Tell me again when the proprietary UNIXes grew these? Was it 1992ish? When did VMS have these? 1982-ish?
Windows: failing to understand that writing a badly-designed wizard is not the same as innovation since 1995.
