READING LARGE DOCUMENTS ON COMPUTERS - Maybe E-paper, E-ink, Kindle, Ebook Readers, Or Just PRINT IT?

I deal with megatons of PDF docs e.g. datahseets, manuals, etc. It's mostly text. As I've been doing computers for decades & health is my priority, not something in "background" I have SUPER healthy environment such as all-black background, silver-colored fonts, no distractions/graphics, brightness at zero, contrast at comfortably low setting which is in hardware + nVidia videodriver, my graphics is 512MB nVidia GeForceMobile. It's too long to explain but everything is as good as it gets.

The bright ideas don't arrive into your head in the office, in bright light while a bunch of people swarm around, you can hear peeing in the toilet, PHONES, etc. I use earplugs 34NRR rating, blue things that far exceed so-called noise reduction headphones (which are a ripoff).

Do you kno whwere bright ideas get born? In a park, woods, the bench, MY CAR - the best, I sit alone in total silence, no cellphones, no dorks of my neighborhood - I just drive out to s State/National Park and that's where I work on complex problems. I need all these PDF's with me. Printing is not an option you obviously understand. One Datasheet for Microchip PIC18F4420 is 421 pages, and I need like a dozen of things of this sort with me.
