I didn't vote because I am never in an area where I need to worry about this kind of thing. The most public place I ever bring my laptop is into work with me. I work in an office where there are plenty of people around that I can trust...
...or so I think...
I suppose if I did take it to a library or something and had to use the bathroom, I'd just ask someone to watch it or something, or knowing me, I'd make a big scene and shout (yes, shout in a library), "MAN I GOTTA PEE! I GUESS I'LL JUST LEAVE MY LAPTOP HERE UNATTENDED WHILE I RUN TO THE RESTROOM! SURE HOPE IT'S HERE WHEN I GET BACK!"
No one is dumb enough to gank a laptop after an episode like that.

Is "gank" only used around where I live? Because it sure feels like it came out of nowhere several years ago and I've never heard it used outside of my own circle of friends.
