Used with the Obok DeDRM plugin, Calibre can easily strip DRM from ebooks bought from the Kobo store. The combo works fine, but it has two downsides: you need to have access to the machine running Calibre, and you must connect your Kobo reader to the machine. While these are not deal-breakers, Kobodl provides a more elegant solution for downloading Kobo ebooks and liberating them from the DRM shackles.
