For starters, every machine running OS X, every iPhone/iPad/iPod Touch, every Apple TV, every AirPort Extreme/Express/Time Capsule that's running NetBSD (rather than whatever small OS was used before they switched to NetBSD), and, as far as I know, every machine running Android.

Then add in servers running Solaris and newer versions of AIX, and PC's running Linux/*BSD/Solaris.
