There is no doubt that Calibre’s success majorly depends on those varieties of plugins and Alf’s DRM Removal plugins are the super stars among them. But many people are saying the Calibre’s interface and user-experience are not that friendly for tech noobs. No mention the plugin installation, which would be another challenge for them.

I have to mention that many vendors have strength their ADE DRM to force readers to download eBooks via ADE4.5 which may caused the DRM removal failure.), and the older Mobipocket and eReader ebooks.
