I sort of thought you were talking about saving stuff to "The Cloud".

I use Evernote, which is basically a journalling program that stores on the cloud. I have it on my home computers, iTouch/iPad, and Android, and can access it on the web--it allows me to read and write to the same files anywhere, but also lets me restrict access with a password, so no one sees anything but me.

At one point, I had a boss who used to sneak in and read people's personal computer files after hours--she could never read any of my stuff because I had nothing stored on my computer.
