I'm legally blind and have been happily been using my PRS-505 for a little over a month. The term "legally blind" only applies to a certain level of visual impairment *after* the best correction. In the U.S., it's defined at 20/200 or worse vision in the better eye (if there's a difference between the two) or as a visual field narrower than 20 degrees (normal vision is 180 degrees).

I'm in the process of writing a guide to using the PRS-505 for people with low vision (legally blind but still with some useful functional vision, like me). I've found the small screen useful because I have problems with tracking and it's much harder to get lost on a page when the page is smaller than that of a mass market paperback. I can read on the 505 for far longer than I can read a regular print book with a magnifier, or even a large print book.

I've had the best luck with making my own book files rather than using books prepared by others. Unfortunately, access to most of the files I've used is restricted to U.S. citizens with documented visual or physical disabilities, because of copyright. I don't know of any services in Australia that are similar to the ones I use.
