Really? I hadn't noticed the epubs bit. I've always downloaded PDFs, so I suppose I just didn't give a shit. I'll give it a try, though I suppose PDFs just annotate better (speaking out of my as here, I'm salivating at the thought of the Apple Pencil), and more reference managers support them over epubs. I hate printing papers. I, unfortunately, have a certain level of OCD when it comes to paper and print quality, and most printers I've come across just don't print that well and buying the kind of paper I prefer to hold is just difficult. Mind, this only manifests if I have to write on that paper. My thresholds for books is much lower. I've gone over to the Kindle a while ago and I've never looked back for non-technical writing, so even that shows itself less and less. Paperless FTW. I'm perfectly fine reading papers on my laptop. I just prefer lying down, reading and annotating, something I've begun to realise the iPad is just perfect for. You'd only do that if you're a masochist. The results always manage to be horrendously weird for me, though maybe this is a function of the software I've used for this. Calibre.
