Are my findings correct, that iBooks for Mavericks only syncs purchased books? I have been anticipating iBooks on Mavericks for months, thinking I'm going to sync my PDF files between devices. I have menus, recipes, manuals, work related material, etc, all in PDF format. And now I find that none of these will sync at all? At least with iTunes I could copy a PDF to my iTunes library, and then when I synchronized with other devices, the PDF would be copied. Now I can't even do that! I should have expected as much from Apple. At least with kindle you can download PDF files from the cloud to all of your devices!
