Hi, I've always liked paper books for educational and entertainment reading, but having gotten a Note 2 last year, I've really come to like reading novels on it with the kindle app. So that has made me think about what is better for more professional/technical books. What do you prefer? What format? PDF or epub/mobi? To be clear, I'm not going to use my phone to read these types of books, my Note 2 is just for light fiction reading. I've tried searching on this, and found some threads about a year old, but I know things can change, so was wondering what the current thinking is. This would be for programming and other IT related books, so I was worried about ease of reading code blocks, and other diagrams/graphics. Bonus question: What hardware do you use? 4:3 Ipad? 16:9 android? Tacos? Any help will be apprecited. I didn't find the right solution from the Internet.
