I specifically purchased my iPad to read the books in my library. The fact that Logos still does not sync my bookmarks from my Desktop and allow me to read on my iPad from where I left off is amazing. All my other ereaders have this feature and as I remember it, Logos advertised it as an advantage of purchasing Logos4. There may be some convoluted, complicated way to work around this difficulty, but as I can with my Kindle, I simply should be able to bookmark my place on my desktop and be able to pick right up on my iPad. I am extremely disappointed. Please correct me if this is wrong or let me know why this simple function is missing or can't be coded into the program.
