The future of digital reading is in the future.
I don't see myself going back to paper (exclusively anyway), and there's no way I'm going to stop reading (as long as my eyesight holds out), so I imagine I'll adapt (rather easily) to
whatever the future of digital reading brings. Just as I've done from my Palm V, to my Kindle II, to my Nexus 7. No biggie. I'm more interested in the letter than the envelope it comes in.
I don't have a cell phone anymore (smart or dumb), so I hope there's a few more options than that in the future!
