r/Fantasy, On which platform do you do most of your reading, and why?

I'll go first. Paperback. I'm not a big fan of hardcovers, the only time I'd buy them is when it's a collectible. I use my kindle whenever I'm on vacation, or when I'm outta the house. Convenient, and light. And finally, I use my iPhone at work, for short stories, and free excerpts.

What about you?
