For one developer projects (aka side projects) Dropbox is great. I now can switch across many machines I have and don't have to lug around a specific laptop and when I boot up, the latest version of the project is there for me to spend an hour or two on and forget about for another week.

Having said that, DB is not a version control tool. Being how intelligent the HN community is I don't quite understand the point of the post: use the tool for what it's meant to be and save yourself the headache (and a blog post).

BitBucket is perfect for private repositories if you have more than 1 developer and want version control and it's free.
