the way I see it there are two reasons to keep your computer away from other people, privacy and paranoia. I condone privacy because I value my own, which is why I have a separate user account ...
but paranoia ... come on its just a computer. I'm not saying I would hand it over to a random stranger on the street but I would never say no to a friend or acquaintance ... I mean come on. I"ve actually given my laptop away for a whole weekend and just used a PC because my friend needed it for some reason or another.
but I stress this once again, its just a computer.
I was thinking about this same issue with cars. When you are young your car is probably your largest asset, and when someone asks you to use it, you start thinking about what if they crash it or what if this or what if that ... the older you get the more apt you are to just toss a person your keys. Its much more refreshing to just not worry about the what ifs ...
