I prefer to get physical books when I can, but I have so many gaming PDFs that I've gotten as bonuses from Kickstarters, humble bundles, etc I feel I might as well read them. It's just the experience of reading them has never been ideal for me. They're often too big and annoying to read on my phone, so there's a lot of zooming in and scrolling. I could use a full laptop, but then they're harder to hold while cuddling on the couch under a blanket or while in bed, like I would a book.

Is there any particular device people prefer for this? I'm guessing a large screened tablet but not too expensive, doesn't need too many bells and whistles since it's for a fairly simple purpose, but should be quick and responsive when loading full color pdfs or turning their pages.
