Now finally with iOS 9.3 and the OS X update I can start to use iBooks. I am happy as I like the look and feel of iBooks but I could never use it as it didn't allow me to sync PDFs and books that I had downloaded from the internet. Now with iCloud sync I have all of my PDFs and books synced across my iPad, mac and iPhone. Works well, haven't had any issues and I am enjoying using iBooks. The best benefit for me is iBooks on the Mac. It is a nice place to store and organise books and PDFs for reading. Much nicer to use than a dropbox folder, I can see all of my books laid out on a bookshelf and can easily search and sort them. Anyone else happy with the change?
