One of the features WordPress.com doesn't offer on a free plan is a proper backup that can be restored to another WordPress instance. Posts/Pages/Comments and Media can be exported, separately, but for a proper backup you need to fork over $180. I have an old site on their $13/yr custom domain plan that I'm probably going to let die this year because I don't wish to keep paying for it and it's not worth that hassle to restore to its original state on my own server.
