This (via PV) is an aggravating article by a fellow who is losing his sight about how using DRM really screws him. It's something to think about before you check that little DRM box on Amazon (hint: I don't). DRM is something that tech-savvy people (including actual pirates) can break in about a minute, so it really serves no purpose except to punish granny for her macular degeneration. E-books have the potential to be a huge boon to the visually impaired, so please don't do things like add DRM (or set your fonts so they can't be changed) that make life even more difficult for people.
