I’m running all kind of different OSs ond different machines, so keeping documents ins sync is a challenge. I was using Dropbox for some stuff since some time and recently moved all my Documents to Dropbox and now only hav Symbolic links in my Documents Folder (Accept for some Subversion Repositories, which are in sync anyway). It works perfectly! I was kind of curious how Dropbox would handle a large number of files but it works.
So everybody who is, like me, running Ubuntu (Netbook and Work PC) and Mac OS (Main Computer) in parallel, check out Dropbox
