Hi all, Question is in the title really. I own a few Macs for University, and also have an iPhone, android tablet and a windows tablet/laptop hybrid (ASUS T100 Chi). I want to know if there is an app that will sync my eBooks / PDF books as I am planning on purchasing PDF versions rather than actual textbooks due to cost savings and weight savings. Furthermore, can the App sync any highlights I make of the PDFs, take down notes (I don't need hand drawn notes, maybe how iBooks allows you to add notes to ebooks, i.e, you can highlight a bit of text and add notes to a popup box) and bookmarks? I understand iBooks can do this for eBooks, but 95% of the books I plan to purchase are simple PDFs. Worst case scenario, I can get an iPad if there is no Android app available by selling my Android tablet, and can possibly live without a Windows app, but Mac and iOS are a must as I spend the majority of my time on my Mac and iPhone. Many thanks!
