Comment 18 for bug 36017

Jakub, thanks a lot. This icon is indeed more recognisable than the previous one.

As a side not, I will add that I disagree with you about the metaphor. Changing
the Floppy disk metaphor was a good one because most of new users have never
seen a floppy disk. (I was astonished to see that but it's real !) Asking them
to click on a floppy-disk is a non-sens and Tango project successfully changed
that ! That a great step.

Unlike the floppy, most people have already seen a lock. I think that if you
show a lock to an user, he would think : I cannot access this unless I have the
key ! That seems a perfectly good behaviour to describe a secure wireless network.

In my mind, the shield is more a metaphor of "protecting myself". For example,
the famous McAfee Antivirus.

But it is of course only my opinion and I'm not an artist at all. You have more
experience and a whole usability lab, don't take my word too seriously ;-)
