I'm good with wikipedia, terrible with PDFs. I'm ok when it's on
   the computer, but once I print them out on paper, I get sleepy
   reading them.

   I've thought about a book reader; my mother has a really
   lightweight one that she loves - a nook I think - so lightweight
   it can actually qualify as electronic paper, unlike most of the
   readers which are crippled Androids, optimized for book reading.

   I still look forward to a waterproof, motion and light charging,
   touch screen reader that's about three millimeters thick, you
   can fold or roll up and it survives, and is tearproof and cheap
   enough to throw in the garbage.

   I'm thinking I'll be dead by the time someone does it, but
   someone will make it. It can't replace paper 'til someone can
   line a birdcage with it tongue emoticon   I first wrote up that
   idea for an Internet dumb terminal way back in 1990. I sat at
   the green screen and dremed of electronic paper. Oh and
   holographic too; the tearable one anyway. Each part could work
   as a full screen; but I knew that part was only a dream. I think
   without the tearable holographic part, the rest is plausible
   engineering.
