Comment 89 for bug 439448

@rupert and Christian: Sorry guys, but what do you mean "it can effectively lock an inexperienced user in to their system with no way of exiting"? All one has to do is press CTRL-ALT-DEL and the shutdown window will pop up. if "Ubuntu is also aimed at the average non-techie user coming from Windows" then that user knows of the key combination and will instinctively try it right away.

Cheers,
Rex
