I recently had my laptop replaced under warranty. They asked if I wanted to migrate everything over from the old hard drive to the new. I realized that I didn't need anything migrated because all my files were on Dropbox, it was pretty nice. When I received the replacement, downloaded Dropbox and everything was there like it was before. Just needed to install some programs.
