One of the uses for it is on the login screen. Pressing ctrl-alt-delete there is a safety feature. Since no application can catch/override it, you can guarantee that if you press the key combination, you will either see the real login screen (not some malware pretending to be the login screen) or the system menu (if you were in fact not at the real login screen).
This feature actually has a name and satisfies some "secure computing" criteria, but from vague memory I thought that Ctrl-Alt-Delete in a Windows session brings up the task manager, or perhaps asks you if you want the task manager. Is that the "system menu"? And out of interest, how can no application be able to trap that combination? Surely these are all normal keys.
Nevertheless, Ctrl-Alt-Delete still has negative connotations. Maybe all our systems should have a BBC Micro-style Break key or a Torch Triple-X-style "soft" power button for situations like this.
