Yeah, some of us made that miskate years ago. I can transfer mp3 just fine, why can't I transfer a book file too? Lots of people entire book libraries are being held hostage by Amazon.
DRM ripping was a pain, I used some sketch program that had only worked with a specific old version of Kindle for PC to turn all my books into ebubs.
I love my kindle, but not buying books from Amazon anymore and next ereader won't be kindle.
Fun unrelated fact, kindle unlimited books could also be downloaded for USB transfer.
I knew it! Sharks are a lie!
