I have a 2013 rMBP 15". I am planning on getting an iPad pro 12.9. When I see conversations about the iPad replacing a notebook, I wonder if it's possible for me. But I wonder how to deal with some files. I have to rely on the cloud for most documents. But movies and music confuse me. If I want to rip a CD or DVD (as a legal owner), how would I get it onto a iPad without a laptop if I gave that up? Right now I import to iTunes on the laptop and sync to iPhone or current iPad Air 2. If I buy through iTunes it's a no brainer, but I still buy discs so that I may share with others. So how do the folks that "replace" their laptops with iPads deal with this type of scenario? What am I missing?
