Hello, I'm looking for an app, maybe you can help me. I'm reading a lot of PDF files for my IT certifications. I don't have my ipad with me all the time, so I'm looking for an apps that exist on IOS and on MAC/Windows. This way, I can read my books from home on my ipad and when I'm at work I can use my windows pc to continue reading. I do a lot of annotations, so I'm looking for an app that I can upload the file in the could and continue where I was, whatever platform I'm using. iBooks on Mavericks would have been nice but no windows support. I though of Kindle for PC but it doesn't support personal files on windows... So do you know a cross-platform reading software with clould and annotations support ? Thanks !
