I'm kind of a knuckle-dragger too when it comes to technology. I don't know anybody who didn't own a microwave before us, and ditto a VHS player (We came around more quickly to the DVD thing)
I use desktop 99% of the time, but if we're out of town I'll use my phone to read only, but my land I have no idea how folks read very much on these things. I would think if you don't have poor eyesight you will after spending your life on these little things. Mines an iPhone 5 and the screen is about like the size of a playing card.
