Alex, I would encourage using literature if you already enjoy reading in general. Outdated or not, there is always somthing to be learned, for there is always someone who knows better than us. Hell, you can buy Doyle Brunsons Super System, in paper back, brand new off the shelf today. That book was published something like 50 years ago.
Remember books ain't always cheap and there is A LOT of free info online.
But personally, I enjoy paper. Being able to write my own notes in ink, and flipping back to reread certain nuggets of info.
We really should unplug more anyway.
