Dropbox offers a few advantages over rsync: It runs in real time and detects changed files, syncing them instantly without polling the filesystem. (using services like inotify). It has iPhone and Android clients. It's easy to install and doesn't carry other requirements like cygwin, and doesn't break in all kinds of odd corner cases like rsync on windows does. It offers central management of which computers sync which files and folders (well, SugarSync does this much better). It offers a web based view of your synced files for when you don't have your own computer. (This can be a plus or minus depending on your viewpoint). It keeps backup copies of your deleted and changed files.
You do know that Dropbox is already using rsync, right? Look at the code... it's available. They wrapped some service logic around it, but it's rsync (librsync) under the hood.
