Dropbox does not sync well. I always end up with tons of files like "Person As copy of file x at date y". It only works if you are "working" alone with a folder and if you only use one device at a time. The problem is that this is the only way to handle sync safely unless you want to manually merge as in a SCM. This is why every attempt at syncing since the dawn of IT has always sucked.
