Unless you're superhuman or very young and medical science advances faster than I think it will, at some point in your life you're going to lose some or all of your sight. I'm 50 and for the last decade I've been noticing significant degradation in my vision. I do that "old guy" thing of pushing my glasses up and holding small print really close to my nose so I can make it out. The fine control muscles in and around my eyes have lost a lot of their strength and flexibility with age.

The good news is that there are an ever-increasing number of devices and software to help with this; the bad news is that DRM screws up almost all of them. This is detailed in heartbreaking depth by Rupert Goodwins on ZDNet in the third part of his essay series. (The essay links you back to parts 1 and 2.) Goodwins particularly calls down a plague upon the house of Adobe but notes many others share blame. And he describes how he, like so many people who are generally law-abiding but want access to their paid-for content, is reduced to petty crime simply because he loves to read.

I'm working on my talk for NE Library in a couple weeks and DRM will definitely feature prominently.
