Dropbox as a Git Remote Repository

I have been experimenting with various methods to synchronize my personal projects with my home PC and my laptop. Exporting, importing, making changes, and again exporting........this has been a real headache especially the huge mess it creates with all the dependency issues that I have to resolve every time.  Of course the use of version controlling would be best solution as many of the developers out there would agree. But still the private repositories are not for free (eg GitHub), so it is out of my scope since I still cannot afford one :'(

Here's my most 'recent' solution and the probably the best so far, ie. maintaining a git remote repository in a file hosting service such as Dropbox or Google Drive. I'm a beginner to learning Git. At the beginning I did some silly mistakes like using Git clients which made learning git far more complicated; I still hate EGit - the eclipse default git client :-@  but once I switched to good old fashioned command line it all made sense.
