My laptop has a built-in fingerprint-reader. So when I wipe one of my fingers over it, it'll fill in stuff like passwords and usernames on websites for me. It works excellently!
I ofcourse went a little further and now when I wipe my middlefinger, it will start up my home-made tools to take over networks and computer remotely from anywhere in the world, as long as I have an internet connection.
So now when a client calls me up and requests assistance with something, I can literally give them the finger.
