There are books that I cannot obtain in the bookstore or amazon prime. For those books I'd like to be able to access them wherever I am (from all my devices, even if I get a new mac book). I also wish to be able to save all the notes in them and have that accessible. I assume one would new to sync in the cloud.
Is this possible?
I see the pdfs are in my computer's readers but I cannot have them sync between devices like, say, mendeley or evernote would.
kindle isn't important. What is important is that my pdfs are available everywhere. Ideally backup with annotations. That doesn't seem to work on either. Thats the crux of my question. Which app is mostly irrelevant.
Note that I strongly prefer to have have it work on 1) kindle or 2)iBooks in that order if possible but if it works on either that would be fantastic.
