Epubor Kindle DRM Removal is a powerfull software to remove DRM protections from Kindle for PC/Mac with no quality losing.Just remove the AZW/PRC DRM header, no change on the files.
Apple recently announced that they will adopt epub as the main format for ibooks(which is a pleasant apple app for ipad/iphone/ipad to read and buy books from itunes book store). no doubt this act would cast a ray of hope for readers who's anxious for an universal format for ebook format, since epub file format has been supported by nook for Barnes and Noble, Sony reader and recently apple, it seems that epbu format has just made the industry standard. But wait... The reality is, even with the same ebook format, there's no free transportation between these devices, because the epub files purchased from itunes, Barnes and Noble and Sony are under different DRM systems which dictates that books can only be supported by certain e-reader exclusively.
For preventing motion pictures or musics from unauthorized redistribution, DRM is an understandable solution to protect creators and publishers, but to books, i beg to differ, the point of digital books is to enhance people's ability in reading, provide convenient access to library and reduce the limitation for readers, anything, anytime and anywhere.
There's also Amazon kindle, by far the most prominent books publisher as well as e-reader manufacturer. Who's clinging to its own azw file that can not be supported by any other readers(kindle books can be read on ipad/iphone/ipod after installed with kindle app).
As per said, the purpose of DRM protection is to prevent unauthorized redistribution or selling illegally copied media on street corner, i personally think if it is for personal use(NOT PIRACY), ebook DRM removal is acceptable
