I have a kindle. I love it. As a san francisco resident, library support for e-readers means I have a queue of books I've flagged as want-to-read that pop up frequently. Two clicks later - they're on my kindle for free (well - my tax dollars well spent, let's say). I also have old books I've bought on amazon and elsewhere (using calibre software to convert other formats, and there exists drm-removal software if you're worried about losing access to the kindle book). In short: I usually walk around with my current two or three books that I'm reading, plus several dozen Comfort Books that I could re-read for the Nth time if the mood strikes me, in a very convenient form-factor that doesn't need light. On the other hand (as other people have said), I read complicated PDFs (usually role-playing game supplements), Comics, and technical books on a phone / laptop / tablet, depending on what's handy. In those cases it's not about the ergonomics of long-term reading, it's about having a responsive color screen.
