All good points, but the same could be possible on a normal login screen without the need for a "shield".

One thing it does very well is showing you all the things you missed
while you were gone.

I used to miss notifications before, because I wouldn't always think
about looking at the message tray for stacked notifications which had
been sent while I was gone.

With the shield, I can quickly see if I received a chat message, or
anything else, as soon as I go back to the computer.

Plus, my girlfriend can now pause my annoying music without having to
call me so I enter my password, which she likes.
