Here's the thing, I'm an iOS/OSX user and I've been watching my friends using android and now I want to buy an android. I want to buy a tablet for college GNote 10.1 I want to know a bunch of things, and I'll be asking a lot! Mainly, I know I can make a "book", I think its called that, which I want to use to write my notes in per subject but I really want to know: 1) How can I add a page? 2) What is my limit of pages? 3) Most importantly, how can I save it on my Mac? I mean backup my notes? Or if I can't, can I export my "books" as a PDF/word and how?
