I am a Commuter with Disabilities. I live in suburban New Jersey and I work in Tribeca. I can experience an incapacitating level of fatigue. I am very sensitive to the amount of weight that I carry on my daily rounds. I also get a lot of my reading done away from home.
Working for BMCC has given me borrowing privileges at New York Public Library, or more specifically http://ebooks.nypl.org (which is one of the busiest branches in the NYPL stystem). My library also has a very strong collection of e-books. I've been spoiled. As long as I'm not hugely specific (there are still a lot of titles that are not available to borrow as e-books), there is always tons to read.
I am also a geek, which means that I will carry a tablet anyway, to display digital content (PDFs etc), and keep my journal.
Am I not the only one who has found ebooks much easier to deal with? I don't have to prop it open. I don't have to store it, dust it, or find a new home for it.
