I was thinking of getting an e-ink reader to keep in my tool box with all of my electronic service manuals on it. I had it narrowed down to the Nook Touch. I like it's rubberized coating, touch screen so few buttons in which to get grime trapped, obvious advantages of e-ink (easy to read, long battery life). I've been poking around about it however, and these 6" eink readers get really bad marks for pdf files. I hear the Nook can be rooted and I'm not shy about doing that. Doing so gives more options as far as which app you can use to read the pdfs. What I'm most worried about is how will these things work when I need to zoom in on an image or diagram. Does anyone have any experience in this regard they'd like to share?
I've already read where a 10 inch screen or so is better for reading pdfs. Well, duh. That's really not an option. Got anything else? Would the Kindle be much better for this, or even the Sony?
