I recall I was using Dropbox on Windows 2003 and Mac OS X 10.4. I was student and actively writing Office documents, AutoCAD, NanoCAD, LabVIEW, plenty of cryptic formats. Eventually Dropbox stopped working on Mac OS X 10.4. And I was not student anymore, I was not dealing with folders. As developer I worked with TortoiseHg and BitBucket, Mercurial repositories and reStructured Text wikis. And returned to neither Dropbox nor similar alternatives. By inertia I synchronized with Dropbox, but when Dropbox stopped working on Mac OS X 10.4, it stopped at all. Eventually I've got OS upgrade, but Dropbox already gone and never returned.
