I write fiction. Mostly I do it at home, but I bought a laptop that sits in my office at work and I use it on my lunch hour. To move texts between them I have been using a flash drive, which works fine, as long as I remember to bring it.
As part of our library-wide summer web luau I was told to try Google Documents. So last night I uploaded a story to Google Documents. Today I downloaded it onto my laptop. It lost some formatting, but nothing I can't easily put back. And having an extra copy of my files somewhere is always a good idea. I'll use it more.
