I use Git for version control but for some of my personal projects I also have a copy in Dropbox, so I can make changes on my laptop downstairs, not be ready to commit it, save it, go upstairs, and continue work from my desktop pretty much seamlessly.

Some of my projects aren't set up this way, and it can get annoying to have made a few small changes and be forced to commit them in order to pull them from upstairs.
