Yeah for fiction, the only thing that beats my Kindle Paperwhite is a physical book.
I'm a little surprised that you are able to do all that so well simultaneously on a PC though. Whenever I've tried to do it the context switching between reading the book or other documents and whatever I'm trying to do with it kills me. Maybe it is because I've only tried to do it on laptops (I don't have a desktop PC) but I also prefer just browsing the web on my phone than on my laptop so maybe I'm just weird.
