Dropbox is flawless for me and very fast. If I edit a doc in dropbox on pc 1, with pc 2 also on, I hear the synched chime with seconds as the edit is uploaded and synched. But I use only a one way back up into dropbox for calibre files, I do not keep the live library there. I use dropbox live for things like to do lists, and for gaming related stuff, and to go between tablet and pc. Google sync is much slower, and there is no fire tablet app.
