I am getting to where I like electronic documents over paper ones. I started reading eBooks in 2009, and have not purchased a paperback/hardback book since. I read two weekly magazines exclusively by electronic means.
The other day, I was helping my granddaughter with her math, and the print in her math book was so small, I could not read it (yes, I need new glasses). The next time we study together, I am going to scan the pages of her book to .pdf so I can read them better on my PC.
Oh, and my default printer has been Adobe Acrobat since 2005. I always ask for electronic documents emailed to me versus mailing me a paper version by snail mail.
