I’ve managed the kindle library for my wife and I on two devices for close to 10 years and I’ve never dealt with syncing or file systems full stop. I hit “buy” on amazon and about 15 seconds later the book is on the kindle and ready to read. There _is_ no management to do.
To clarify this is managing my own library rather than buying books off Amazon. I tend to buy books locally and pirate the ebook copy which I sync from my computer. I don't feel inclined to line Amazon's pockets any more than I already have...
